Question

Pointing to a man, a woman said, "His mother is the only daughter of my father." How is the man related to the woman?

1. A. Son (Correct answer)
2. B. Nephew
3. C. Cousin
4. D. Grandson

Correct Answer

Option A — Son

Detailed Solution & Explanation

The correct answer is Son.

Key Points

• 'The only daughter of my father' is the woman herself.
• So 'his mother is the only daughter of my father' means the man's mother is the woman, which makes the man her son.
• Collapse self-referential clues first ('only daughter of my father' = the speaker), then read the remaining relation directly.
