Break down the coded expression from left to right and map each symbol to its gender and familial role immediately.
Decode First Relation (A + B)
The symbol + means daughter. Therefore, A + B indicates that A is the daughter of B, which means A is female.
Decode Second Relation (B x C)
The symbol x means husband. Therefore, B x C indicates that B is the husband of C, meaning B is male and C is female.
Determine Final Relation of A to C
Since B is married to C and A is the daughter of B, A must also be the daughter of C.
B: Wife is incorrect because A is the daughter, not the spouse of C. C: Sister is incorrect because A belongs to the subsequent generation. D: Mother is incorrect because C is the mother and A is her child.
A is correct because A is the daughter of B, and since B is married to C, A is the daughter of C.
