Step 1: Understanding the Concept:
We must construct a 3-generation family tree. From point 3, A (Male) is the son of C and father of E (Female). From point 4, F is the mother of E, which means A and F are a married couple. D is F's daughter, making D and E sisters.
Step 2: Detailed Explanation:
- Generation 1: C and B (The grandparents). Since A is the son of C, and there are 6 members, B must be C's spouse.
- Generation 2: A (Husband) and F (Wife).
- Generation 3: E (Daughter) and D (Daughter).
Step 3: Calculation:
The "children" in the family are D and E. Their biological parents are A and F.
Step 4: Final Answer:
The parents of the children are AF. Thus, the correct option is (e).
