Explanation:

Let’s analyze the seating arrangement step by step:

- A sits second to the left of B.

- Only two people sit between A and H.

- G sits third to the right of H.

- E sits immediate left of G.

- D sits second to the left of C.

- F sits third to the right of C.

Let’s see the group:

- H-C: H and C have one person between them.

- F-H: F and H are positioned with others in between, not adjacent.

- B-A: B and A, A is second to the left of B.

- A-G: A and G, their positions not immediately next.

- G-F: G and F, also with distance.

All except B-A have a separation (not immediate next). Only B-A have a direct placement (second to the left), so it stands apart.

So, the answer is Option 3, B-A.

Correct answer:

Option: 3, B-A

Explanation (in brief):

- Options 1,2,4,5: All pairs are neither immediate neighbors nor have a consistent seater-count between them.

- Option 3: B and A have a fixed seating relation (A sits second to the left of B), which is different from the others.
