Which of the following BEST describes the friends sitting on chairs adjacent to the one occupied by Bashir at the end of Turn 7?

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start			7	2
T1 — Aslam
T2 — Bashir
T3 — Chhavi
T4 — Davies
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Davies start $= 2$ and Chhavi start $= 7$ are filled from clue 2.

Davies first moves in Turn 4, so the statement that Davies is on chair $2$ after Turn 1 means Davies begins on chair $2$.

Chhavi first moves in Turn 3, so the statement that Chhavi is on chair $7$ after Turn 2 means Chhavi begins on chair $7$.

---

Davies is isolated (empty chairs on both sides), so chairs $1$ and $3$ are empty in the starting position.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam
T2 — Bashir
T3 — Chhavi
T4 — Davies
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Aslam start $= 6$ and Bashir start $= 4$ are filled.

Aslam sits next to Chhavi (chair $7$); the neighbours of $7$ are $6$ and $1$.

Chair $1$ is empty, so Aslam $= 6$.

---

Bashir must be isolated and can only use a remaining chair.

Chair $5$ has neighbour $6$ (Aslam) occupied, so it is not isolated.

Chair $3$ is empty.

Chair $4$ has neighbours $3$ and $5$ both empty, so Bashir $= 4$.

Starting empty chairs: $\{1, 3, 5\}$.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir
T3 — Chhavi
T4 — Davies
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Aslam moves from chair $6$.

Clockwise: chair $7$ is occupied, chair $1$ is empty $\to 1$.

Counterclockwise: chair $5$ is empty $\to 5$.

---

Clue 1 requires the four to be consecutive after Turn 2.

If Aslam $\to 5$: occupied $\{2,4,5,7\}$, and Bashir (T2) from $4$ can reach $3$ giving $\{2,3,5,7\}$ or $6$ giving $\{2,5,6,7\}$ — neither is four consecutive chairs.

So Aslam $\to 1$ (clockwise).

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi
T4 — Davies
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Bashir moves from chair $4$ (empty chairs now $\{3,5,6\}$).

Clockwise: chair $5$ empty $\to 5$, giving occupied $\{1,2,5,7\}$ — not consecutive.

Counterclockwise: chair $3$ empty $\to 3$, giving occupied $\{1,2,3,7\}$, i.e. chairs $7,1,2,3$ — four consecutive.

Clue 1 requires consecutive chairs at Turn 2, so Bashir $\to 3$.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Chhavi moves from chair $7$ (empty chairs now $\{4,5,6\}$).

Clockwise: chairs $1,2,3$ occupied, chair $4$ empty $\to 4$.

Counterclockwise: chair $6$ empty $\to 6$.

---

If Chhavi $\to 4$: occupied $\{1,2,3,4\}$, four consecutive — this would violate clue 1, since consecutive seating is allowed only at Turn 2 and Turn 6.

So Chhavi $\to 6$. This also keeps chair $4$ free, which Davies will need next.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies	1	3	6	4	1,3,4,6
T5 — Aslam
T6 — Bashir
T7 — Chhavi

Davies moves from chair $2$ (empty chairs now $\{4,5,7\}$).

From clue 2, Davies is on chair $4$ after Turn 5; since Davies moves only in Turn 4, Davies must reach chair $4$ now.

Clockwise from $2$: chair $3$ occupied, chair $4$ empty $\to 4$.

So Davies $\to 4$. Occupied $\{1,3,4,6\}$ is not consecutive, consistent with clue 1.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies	1	3	6	4	1,3,4,6
T5 — Aslam	7	3	6	4	3,4,6,7
T6 — Bashir
T7 — Chhavi

Aslam moves from chair $1$ (empty chairs now $\{2,5,7\}$).

Clockwise: chair $2$ empty $\to 2$.

Counterclockwise: chair $7$ empty $\to 7$.

---

Clue 1 requires the four to be consecutive after Turn 6.

If Aslam $\to 2$: occupied $\{2,3,4,6\}$, and Bashir (T6) from $3$ reaches $5$ giving $\{2,4,5,6\}$ or $1$ giving $\{1,2,4,6\}$ — neither consecutive.

If Aslam $\to 7$: occupied $\{3,4,6,7\}$, and Bashir (T6) from $3$ can reach $5$ giving $\{4,5,6,7\}$ — consecutive.

So Aslam $\to 7$. (Davies remains on $4$, matching clue 2.)

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies	1	3	6	4	1,3,4,6
T5 — Aslam	7	3	6	4	3,4,6,7
T6 — Bashir	7	5	6	4	4,5,6,7
T7 — Chhavi

Bashir moves from chair $3$ (empty chairs now $\{1,2,5\}$).

Clockwise: chair $4$ occupied, chair $5$ empty $\to 5$, giving occupied $\{4,5,6,7\}$ — four consecutive.

Counterclockwise: chair $2$ empty $\to 2$, giving $\{2,4,6,7\}$ — not consecutive.

Clue 1 requires consecutive chairs at Turn 6, so Bashir $\to 5$.

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies	1	3	6	4	1,3,4,6
T5 — Aslam	7	3	6	4	3,4,6,7
T6 — Bashir	7	5	6	4	4,5,6,7
T7 — Chhavi	7	5	1/3	4	1,4,5,7 / 3,4,5,7

Chhavi moves from chair $6$ (empty chairs now $\{1,2,3\}$).

Clockwise: chair $7$ occupied, chair $1$ empty $\to 1$, giving occupied $\{1,4,5,7\}$.

Counterclockwise: chairs $5,4$ occupied, chair $3$ empty $\to 3$, giving occupied $\{3,4,5,7\}$.

Neither set is four consecutive chairs, so both directions satisfy clue 1; Chhavi's Turn 7 destination is not pinned down.

---

Either way, Chhavi leaves chair $6$, so chair $6$ becomes empty.

Bashir stays on chair $5$; its neighbours are chair $4$ (Davies) and chair $6$ (empty).

Turn	Aslam	Bashir	Chhavi	Davies	Occupied
Start	6	4	7	2	2,4,6,7
T1 — Aslam	1	4	7	2	1,2,4,7
T2 — Bashir	1	3	7	2	1,2,3,7
T3 — Chhavi	1	3	6	2	1,2,3,6
T4 — Davies	1	3	6	4	1,3,4,6
T5 — Aslam	7	3	6	4	3,4,6,7
T6 — Bashir	7	5	6	4	4,5,6,7
T7 — Chhavi	7	5	1/3	4	1,4,5,7 / 3,4,5,7

The table is complete.

All positions are uniquely determined except Chhavi's destination at Turn 7, which can be chair $1$ or chair $3$; both satisfy every clue.

This ambiguity does not affect Bashir, who ends on chair $5$ with neighbours chair $4$ (Davies) and chair $6$ (empty) in either case.

---

At the end of Turn 7, Bashir is on chair $5$ (he last moved in Turn 6 and does not move in Turn 7).

The neighbours of chair $5$ are chair $4$ (Davies) and chair $6$. Chhavi has just left chair $6$ in Turn 7 (to chair $1$ or chair $3$), so chair $6$ is empty in both possibilities.

Thus the only friend adjacent to Bashir is Davies.

Answer: Davies only — option 4.
