If $\text{P+Q}$ mẹans $\text{P}$ is the mother of $\text{Q . P # Q}$ means $\text{P}$ is the father of $\text{Q. P – Q}$ means $\text{P}$ is the sister of $\text{Q}$, then which of the following relationship shows that $\text{M}$ is the daughter of $\text{R}?$

1. $\text{R # M + N}$
2. $\text{R + N # M}$
3. $\text{R - M # N}$
4. None of these

Option (A) is correct.

$R\#M+N$: $R\#M$ means R is the father of M (R is male).$M+N$ means M is the mother of Q. M is the daughter of R and Q is grand child of R.
