Correct Answer & Explanation
Option D
Let's trace the relationships:
• A is the son of B. (B is A's parent)
• C is the daughter of A. (A is C's father)
• D is the mother of C. (Since A is C's father, D must be A's wife)
• E is the brother of D.
Now, we need to find the relation between B and E.
• E is D's brother.
• D is A's wife.
• A is B's son.
So, B is A's parent. E is A's wife's brother. We don't know the gender of B. If B is male, B is E's father-in-law. If B is female, B is E's mother-in-law. Since B's gender is not specified, the relationship cannot be determined definitively.
