Given:
K + M means 'K is the daughter of M'.
K - M means 'K is the husband of M'.
K × M means 'K is the brother of M'.
Coded relation: T × V + Z
Now draw a family tree using the following notations:
The relation diagram for the above relation is as follows:
Let us consider each option statement.
1. T is the father of Z → False (T is the son of Z)
2. T is the son of Z → True
3. T is the brother of Z → False (T is the son of Z)
4. T is the uncle of Z → False (T is the son of Z)
Hence, 'T is the son of Z' is the correct answer.
