Read the following information carefully & answer the question given below:

I) 'P+Q' means 'P is mother of Q'
II) 'P-Q' means 'Q is sister of P'
III) 'P×Q' means 'P is the brother of Q'
IV) 'P÷Q' means 'Q is the father of P'

Which of the following means R is nephew of T?

A) R×J÷T
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:

Only (D)

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:

1. R must be Male (to be a nephew and not a niece).

2. 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

• $÷$ = Father (e.g., $P÷Q$ means $Q$ is father of $P$)

Option (A): $R\times J÷T$

• $R\times J$: $R$ is the brother of $J$ ($R$ is male).

• $J÷T$: $T$ is the father of $J$.

• Relationship: $T$ is the father of both $R$ and $J$. Thus, $R$ is the son of $T$.

Option (B): $R\times T÷J\times K$

• $R\times T$: $R$ is the brother of $T$.

• $T÷J$: $J$ 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.
