• B. Set of even prime numbers greater than $3$
• C. Set of Natural numbers less than $0$
• D. Set of Imaginary numbers

Answer 1

The correct option is D Set of Imaginary numbers

$\left(A\right)$ There is no odd prime number less than $3$. So, it is an empty set.

$\left(B\right)$There is no even prime number greater than $3$.So,it is an empty set.

$\left(C\right)$There is no natural numbers less than $0$.So,it is an empty set

$\left(D\right)$Set imaginary numbers$=\left\{iR\right\}$

So, it is a non-empty set.
