(A) and (D) are incorrect but (B) and (C) are correct

✅ Correct Option: 4

Given information about the family:

Six members: A, B, C, D, E, and F
B is the son of C but C is not the mother of B
A and C are a married couple
E is the brother of C
D is the daughter of A
F is the brother of B

Since B is the son of C but C is not the mother of B, C must be the father of B.

Therefore, C is male.

A and C are a married couple, and C is male.

Therefore, A is female (the mother).

The family structure:

C (male) - father
A (female) - mother
B (male) - son of A and C
D (female) - daughter of A and C
F (male) - brother of B, so F is also a son of A and C
E (male) - brother of C (uncle)

Evaluating statement (A): There are only three male members in the family

Male members: C, B, F, E = 4 males

Statement (A) is incorrect.

Evaluating statement (B): A has only three children

Children of A and C: B, D, F = 3 children

Statement (B) is correct.

Evaluating statement (C): A and D are both females

A is female (mother) and D is female (daughter)

Statement (C) is correct.

Evaluating statement (D): D is a female but A is not a female

D is female (correct), but A is also female (incorrect claim)

Statement (D) is incorrect.

(A) and (D) are incorrect but (B) and (C) are correct.

The correct answer is Option 4.
