Show Hint
Always separate the information into "Adults" and "Children" lists. By identifying that the adults are completely accounted for by the two married couples (A-E and D-B), you can quickly focus on assigning the remaining children (C, F, G) to their respective parents.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
We need to construct a family tree based on the given clues about 7 members (A, B, C, D, E, F, G) consisting of 4 adults, 3 children, and identify the identity and relationship of C.
Step 2: Detailed Explanation:
Let us list and analyze the clues systematically:
- Total members = 7 (4 adults, 3 children).
- F and G are girls (female children). Since there are 3 children in total, and two of them are girls (F and G), the third child must be a boy.
- Clue (J): A and D are brothers. Both are male adults. A is a doctor.
- Clue (K): E is an engineer married to one of the brothers and has two children.
- Clue (L): B is married to D, and G is their child.
Now let's reconstruct the relationships:
- Since D is married to B, the other brother A must be married to E.
- Married couples (Adults):
1. (A, E)
2. (D, B)
This accounts for all 4 adults (A, D, E, B).
- Children distribution:
- G is the child of (D, B). G is a girl.
- E (who is married to A) has two children. Since the total number of children is 3, these two children must be the remaining members: C and F.
- Therefore, the children of A and E are C and F.
- Identifying genders of children:
- We are given that F and G are girls.
- This leaves C to be the only boy (son) among the three children.
- Therefore, C is the son of A and E.
Step 3: Final Answer:
(A) A and E's son
