Show answer & explanation
Correct answer: D
Concept: In a blood-relation puzzle, fix each person's gender and generation from the explicit clues, then chain the parent–child and sibling links. A child of a person is that person's son (male) or daughter (female); siblings share the same parents, so a sibling of someone's child is also that person's child.
Application — decode the clues step by step:
A and B are a married couple and A is male, so A is the husband and B is the wife.
C is the brother of A, and D is the only son of C. So D is C's child (male).
E is the sister of D. Siblings share the same parents, so E is also a child of C — and since E is a sister, E is C's daughter.
Therefore E is the daughter of C.
Cross-check: B is the daughter-in-law of F (whose husband has died), and B married A, so F is the mother of A and C. The family is consistent: F is the grandmother, A and C are her sons, and E (with brother D) is a child of C. E being D's sister and D being C's son confirms E is C's daughter.
