Question

A is the wife of B. B is the brother of C. C is the father of D. How is A related to D?

1. A. Aunt (Correct answer)
2. B. Mother
3. C. Sister-in-law
4. D. Grandmother

Correct Answer

Option A — Aunt

Detailed Solution & Explanation

The correct answer is Aunt.

Key Points

• Follow the chain: A is B's wife, B is C's brother, and C is D's father.
• Since B and C are brothers, B is D's uncle (the father's brother).
• A, being B's wife, is therefore D's aunt by marriage.

Additional Information

• Both a parent's sister and a parent's brother's wife are called aunt in English, which is why the answer holds even though A is related to D only by marriage.
• Mother is wrong because D's parent is C, not B; grandmother would require an additional generation that the chain does not contain.
• Sister-in-law describes A's relationship to C, not to D — the options deliberately include a term that is correct for a different pair in the same chain, which is the trap.
• Drawing the chain as a diagram, with B and C on the same horizontal line and D below C, makes the generation gap immediately visible.
