P and Q are a married couple. A and B are brothers. A is the brother of P. How is B related to Q?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Brother-in-law
The relation is built one link at a time, from P to B and then to Q.
A is the brother of P, and A and B are brothers, so B is also P’s brother.
P and Q are a married couple, so B is the brother of Q’s spouse, that is, Q’s brother-in-law.
