A is the son of B. C, B's sister, has a son D and a daughter E. F is maternal uncle of D. How is A related to D?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Cousin Brother
The clues are placed one by one on a family tree:
A is the son of B, so A is male and one generation below B.
C is B’s sister, so B and C are siblings.
D and E are C’s children, so D is the child of B’s sister.
A and D are children of a brother-sister (or sister-sister) pair, so they are cousins, and A, being a son, is D’s cousin brother. The clue about F, D’s maternal uncle, only says that C has a brother; it is not needed for the answer.
