Directions (71-73): Study the following information carefully and answer the below questions:

A is the only son of Q who is the brother-in-law of Y. U is the mother of B but she is not the spouse of Q. Y is the unmarried brother of Z. X is the paternal aunt of B whereas V is the daughter-in-law of A. No single parent has a child and an equal number of males and females are there in the family.

If J is the brother of V, then how is J related to B?

Correct Answer: The correct option is Brother-in-law.

Step-by-step Explanation:

Let's analyze the given clues step-by-step to deduce the family tree:

1. "No single parent has a child": This means every parent in the family must have a spouse.

2. Clues involving Q, A, Y, Z, and U:

- "A is the only son of Q." (A is male, Q is parent of A)

- "Q is the brother-in-law of Y." (Q is male or female, Y is unmarried brother of Z, so Y is male).

- "Y is the unmarried brother of Z." (Y is male, Z is sibling of Y).

- "U is the mother of B but she is not the spouse of Q." (U is female, parent of B).

3. Clues involving A, V, X, B:

- "V is the daughter-in-law of A." (V is female, married to the son of A. Since A has a daughter-in-law, A must have a son who is married to V).

- "X is the paternal aunt of B." (X is female, sister of B's father).

4. Structuring Generations & Relationships:

- Q and Z are married because Q is brother-in-law to Y (Y's sibling is Z, Q marries Z). Since Y is male, Z is female/spouse of Q.

- Q (Male) + Z (Female) are parents of A (Male, only son) and X (Female, aunt of B).

- A (Male) is married to U (Female). Their children are B (Male) and another child if applicable, but B's paternal aunt is X (sister of A).

- B (Male) is married to V (Female), making V the daughter-in-law of A.

5. Answering the specific question:

- The question states: "If J is the brother of V, then how is J related to B?"

- V is the wife of B.

- Therefore, V's brother (J) is the Brother-in-law of B.
