In a family of 6 members, D is the only son of A, E is the grandfather of D. B is the daughter-in-law of C. F is the uncle of D. C is wife of A. What is the relationship of B with D?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Wife
A daughter-in-law is the wife of one’s son, so B’s place is fixed by finding C’s son.
C is the wife of A, and D is the only son of A, so D is the only son of C too
B is the daughter-in-law of C, so B is the wife of C’s son
C’s only son is D, so B is D’s wife

The statements about E (grandfather) and F (uncle) are not needed for the answer.
