Question

Introducing a boy, a girl said, "He is the son of my mother's only son." Who is the boy to the girl?

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

Correct Answer

Option C — Nephew

Detailed Solution & Explanation

The correct answer is Nephew.

Key Points

• Work outward from the innermost phrase. The speaker is a girl, and "my mother's only son" must therefore be her brother — the word *only* rules out any other son.
• The boy is the son of her brother.
• A brother's son is her nephew.

Additional Information

• Contrast this with the near-identical construction where a man says "my mother's only son", which resolves to himself, making the child his own son or daughter. The speaker's gender changes the entire answer.
• Draw a quick diagram — squares for males, circles for females, vertical lines for descent — rather than reasoning in words; these questions are designed to be confusing when read aloud.
• Qualifiers such as only, elder, younger, maternal and paternal are never decorative. Each one exists to eliminate an alternative reading, and missing one usually leads to a distractor.
