Show answer & explanation

Correct answer: D

Interpret P#R*Q@T£V step by step (left → right): P#R ⇒ P is husband of R. (P = husband, R = wife)

R*Q ⇒ R is daughter of Q. (Q is parent of R)

Q@T ⇒ Q is wife of T. (T is Q’s husband)

T£V ⇒ T is father of V. (V is child of T and Q)

So Q and T are parents of R. V is also child of T (and Q). Therefore R and V are siblings. P is husband of R, so P is the son-in-law of R’s parents (i.e., of T). Thus the statement that is definitely true is: (4) P is son-in-law of T.
