In a family, there are six members A, B, C, D, E, F. A and B are married couple. D is the only son of C. A is father of E, who is grand daughter of F, whose husband has died and C is brother of A. How many male members are there in the family?

Correct answer: 4

Explanation: ✅ Correct Answer: B. 4 📚 Explanation: By sketching the family tree: A and B are a couple, C is A's brother, and D is C's son. F's husband has died, meaning she is the mother of A and C. The male members identified are A, C, D, and F's late husband. This results in a total of 4 male members in the family line. Drawing a diagram helps solve these relationship puzzles clearly.
