In a certain code language, 'A + B' means 'A is the mother of B', 'A - B' means 'A is the brother of B', 'A x B' means 'A is the wife of B' and 'A ├╖ B' means 'A is the father of B'. How is M related to T if 'M - N ├╖ P + S x T'?
Brother of the father of the wife's mother
Brother of the wife's father

Analyze M - N
According to 'A - B means A is the brother of B', M - N means M is the brother of N.
Analyze N / P
According to 'A / B means A is the father of B', N / P means N is the father of P.
Analyze P + S
According to 'A + B means A is the mother of B', P + S means P is the mother of S.
Analyze S x T and Final Conclusion
According to 'A x B means A is the wife of B', S x T means S is the wife of T. Since P is S's mother and N is P's father, N is the father of S's mother (i.e., S's maternal grandfather). M is N's brother, making M the brother of S's maternal grandfather, or equivalently, T's wife's mother's father's brother.
B: Wife's father's brother matches a different path without the maternal grandmother link. C: Wife's mother's mother's father involves an incorrect gender/generation jump. D: Wife's father's father's brother assumes paternal lineage instead of maternal.
A is correct because decoding M - N / P + S x T gives M as the brother of N, who is the father of P (mother of S), who is the wife of T, resulting in T's wife's mother's father's brother.
