Decode the family tree from left to right: represent symbols as relationships and trace the lineage downwards to T.
Analyze the expression A # B + H @ K ├╖ T
Break it down: 1) A # B: A is mother of B. 2) B + H: B is daughter of H (since A is mother of B and B is daughter of H, A and H are a couple, A is female, H is male). 3) H @ K: H is father of K. 4) K ├╖ T: K is wife of T.
Identify relationships
A is mother of B, H is father of B, so A and H are husband and wife. H is father of K, so A is also mother of K. Since K is wife of T, A is the mother of K, and K is married to T.
Determine relation of A to T
A is the mother of K. K is the wife of T. Therefore, A is the mother-in-law of T (the mother of T's wife).
A: Wife's sister is incorrect as T's wife is K, not someone related to A's sister. B: Mother's mother is incorrect because A is one generation above T's wife, not two. D: Wife's sister's daughter is incorrect because K is T's wife, not A's daughter-in-law's sister's child.
C is correct because A is the mother of K, and K is the wife of T, making A the mother-in-law (Wife's mother) of T.
