Read the following information to answer the question.
$A+B$ means $A$ is daughter of $B$; $A*B$ means $A$ is son of $B$ and $A-B$ means $A$ is wife of $B$.
If $Z*T-S*U+P,$ what is $U$ to $Z$?
$Z$ is the son of $T$, who is the wife of $S$, who is the son of $U$.
i.e. $Z$ is the son of $S$ who is the son of $U$
i.e. $Z$ is the grandson of $U$
$U$ is the daughter of $P$
So, $U$ is the grandmother of $Z$.
So, option (B).
