Show answer & explanation
Correct answer: B
Key: + means brother of; - means wife of; * means mother of.
Consider M+N - P: M + N means M is the brother of N. N - P means N is the wife of P. Therefore M is the brother of P's wife, i.e., M is the brother-in-law of P. This is the correct expression.
For the other expressions:
M-N+P yields: M is the wife of N and N is the brother of P, so M is the wife of P's brother (sister-in-law of P) — incorrect.
M*N+P yields: M is the mother of N and N is the brother of P, so M is also the mother of P — incorrect.
M-P*N yields: P is the mother of N and M is the wife of P, so M is the spouse of P (not brother-in-law) — incorrect.
Final answer: M+N - P is the expression that makes M the brother-in-law of P.
