A, B, C, D, and E are the five members in a family. Among them, there is one married couple. E is unmarried and is the brother of A, D is the sister of E, C is the only married female and the mother of D. B and E are only males in the group. Who is the father of A?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → B
The clues are placed one by one on a family tree:
E is the brother of A and D is the sister of E, so A, D and E are brothers and sisters.
C is the mother of D, so C is also the mother of A and E.
B and E are the only males, so A, C and D are females. The one married couple must have a husband: E is unmarried, so the husband is B, and C, the only married female, is his wife.
B is therefore the husband of the children’s mother, that is, the father of A.
