B) R×T÷J×K
C) R-M+T-J
D) $T - K + R \times M$

Choose the correct answer from the options given below:

Answer & explanation

Correct answer: option 4

The correct answer is Option 4: Only (D)*

To create a completely correct option where R is the nephew of T, the expression must satisfy two conditions:

R must be Male (to be a nephew and not a niece).
R must be the child of T's sibling (brother or sister).

Using the symbols provided in the rules:

$+$ = Mother
$-$ = Sister (e.g., $P - Q$ means $Q$ is sister of $P$ )
$\times$ = Brother
$\div$ = Father (e.g., $P \div Q$ means $Q$ is father of $P$ )

Option (A): $R \times J \div T$

$R \times J$ : $R$ is the brother of $J$ ( $R$ is male).
$J \div T$ : $T$ is the father of $J$ .
Relationship: $T$ is the father of both $R$ and $J$ . Thus, $R$ is the son of $T$ .

Option (B): $R \times T \div J \times K$

$R \times T$ : $R$ is the brother of $T$ .
$T \div J$ : $J$ is the father of $T$ .
Relationship: $R$ and $T$ are siblings. $R$ is the brother of $T$ .

Option (C): $R - M + T - J$

$R - M$ : $M$ is the sister of $R$ .
$M + T$ : $M$ is the mother of $T$ .
Relationship: $R$ is the brother of $T$ 's mother. $R$ is the maternal uncle of $T$ .

Option (D): $T - K + R \times M$

$T - K$ : $K$ is the sister of $T$ . (Based on Rule II: $P - Q$ means $Q$ is sister of $P$ ).
$K + R$ : $K$ is the mother of $R$ . (Based on Rule I: $P + Q$ means $P$ is mother of $Q$ ).
$R \times M$ : $R$ is the brother of $M$ . (This confirms $R$ is male).
Relationship: $R$ is the son of $T$ 's sister ( $K$ ). This perfectly defines the relationship of a Nephew.
