Analyze M + N
M + N means M is the mother of N.
Analyze N ├╖ O
N ├╖ O means N is the brother of O. Since M is the mother of N, she is also the mother of O.
Analyze O ├Ч P
O ├Ч P means O is the husband of P.
Analyze P + Q
P + Q means P is the mother of Q. Since O is the husband of P, O is the father of Q.
B: Son is incorrect as O is the parent. C: Father's brother is incorrect as that describes N's relationship to Q. D: Brother is incorrect as that describes N's relationship to O.
A is correct because the sequence M+N├╖O├ЧP+Q establishes O as the husband of P, and P as the mother of Q, making O the father of Q.
