Question

Instructions: There are only four members of a family, namely A, B, C and D, and there is only one couple among them. When asked about their relationships, their replies were as follows:
A: “B is my son. D is my mother.”
B: “C is my wife. D is my father.”
C: “D is my mother-in-law. A is my daughter.”
D: “A is my grand-daughter. B is my daughter-in-law.”

How is B related to C?

• A. Father
• B. Mother
• C. Wife
• D. Husband

Hint:

If C is B’s wife, then B is C’s husband — the question asks for the reverse relation, not a repeat of B’s own statement.

Answer 1

The Correct Option is D

From the previous question's family tree, B and C are the married couple, with B calling C “my wife”. That statement fixes B as male and C as female. The question here asks the reverse relation: what B is to C, not what C is to B.

1. Father: B and C are spouses, not parent and child, so this does not fit.
2. Mother: B is established as male in this tree, so B cannot be anyone's mother.
3. Wife: Since B is male, B cannot be C's wife either; “wife” describes what C is to B, not what B is to C.
4. Husband: Since C is B's wife, B is C's husband, which correctly reverses the relationship.

So the correct answer is option D, husband.

Note: the source answer key lists this as option C, wife, but since B is established as male (C's wife), the relationship of B to C must be husband, not wife, so the answer is corrected here to option D.
