Show answer & explanation

Correct answer: D

Concept: In blood-relation puzzles, decode a nested relation phrase from the innermost clause outward — identify each described person, substitute step by step, and reduce the chain until a direct kinship term emerges. A key device is “the only son/daughter of X” — this always points back to one specific individual with no sibling of that gender.

  1. The statement is: “His brother's father is the only son of my mother” (his = the man in the picture).

  2. Full siblings share the same father, so “his brother's father” is simply his own father.

  3. So the statement reduces to: the man's father is “the only son of my mother” — that is, the woman's own brother.

  4. Therefore, the man's father = the woman's brother, which makes the man the son of the woman's brother.

Cross-check: The son of one's own brother is always one's nephew, confirming the relation without relying on any other reading of the statement.

Hence, the man is the woman's nephew.
