Which of the following means 'M is the niece of N'?

• A. $M\times R-N$
• B. $N÷J+M+D$
• C. $N÷J+M$
• D. $N\times J-M$
• E. $Noneofthese$

Answer 1

The correct option is B $N÷J+M+D$

From option (2)

$N÷J+M+D$
$N÷J\to N$ is the sister of J.
$J+M\to J$ is the father of M.
$M+D\to M$ is the sister of D.
So, M is the niece of N.
