Explanation:

Let's break down the arrangement step by step:

- There are 9 members: A, B, C, D, E, F, G, H, I.

- 2 couples. H has 2 sons and 1 daughter. H is sitting third to the right of C.

- A is immediate left of his wife C.

- Members at both ends are B's children.

- B is immediate right of wife H.

- G and I (daughters) sit with their fathers.

- D is brother-in-law of A, in the middle, second to right of A.

- E is immediate right of his maternal uncle D.

- I (granddaughter of H, daughter of C), not at extreme ends.

- I is C's daughter.

Arranging:

1. Couple: A and C (A left of C). Another couple: B and H (B right of H).

2. D is brother-in-law of A (so D married to A's sister or A married to D's sister).

3. H has 2 sons (A and D) and 1 daughter (C).

4. G and I are daughters, G sits with her father, I sits with her father (A).

5. Extreme ends: Children of B.

Final logical arrangement:

A - C - F - D - E - B - H - G - I or similar.

By checking all positions:

- "Who is sitting second to the left of G?"

If G is between H and I, say: ... B H G I ... then second left of G is B.

Option 2, B is correct.

Correct Answer: Option 2, B

- G sits with her father H; B is at the left of G.

- Second to left of G: B (if arrangement is ...B H G...).

- Other options (A, H, I) don’t fit here.
