Explanation:

Let’s break down the information step-by-step:

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

- 2 couples in the family.

- H has 2 sons and 1 daughter.

- C (wife of A): A is immediate left to C.

- Both extreme ends are B's children.

- B is immediate right of wife H.

- Daughters G and I sit with their fathers.

- D (brother-in-law of A) sits in the middle and is 2nd right of A.

- E is immediate right of “maternal uncle” D.

- I is not at the extreme, is C’s daughter and H’s granddaughter.

Key deductions:

- A is married to C. B is married to H.

- B and H are older generation; A & C are likely their kids.

- G and I are daughters, sit with their fathers.

- I is daughter of C, so A is father of I.

- E’s “maternal uncle” is D ? D is C’s brother.

- C must be B & H’s daughter; D is her brother.

Family map (simplified):

- B (m) & H (f): Married couple, children are A (m), C (f), D (m)

- A (m) & C (f): Married couple, child I (f)

- D (m): Sibling of A and C.

- G, E, F: Need positioning, but G is another daughter.

- F likely married to D (since two couples).

Question: How is E related to F?

- E is with maternal uncle D, so E is niece/nephew of D; D is married to F, so E is niece/nephew of F, too.

- Since E is called “he” nowhere and no specific gender given, but context in standard family trees and competitive exams, usually “_Nephew_” (option 4) is correct unless specified otherwise.

So,

- Option 1 (Niece): Can't be determined.

- Option 2 (Son): Not relevant.

- Option 3 (Daughter): Not specified.

- Option 4 (Nephew): Correct.

- Option 5 (Cannot be determined): Not needed.

Answer:

Option 4 – Nephew
