Show answer & explanation
Correct answer: D
Explanation:
Y $ R means Y is the father of R.
R @ T means R is the brother of T. Brothers and sisters share the same parents, so Y (father of R) is also the father of T.
T * X means T is the daughter of X, so X is a parent of T.
Since Y is the father of T and X is the other parent of T, X must be the mother of T and therefore the wife of Y.
