The correct answer is:
Both $\mathrm{X}$ and $\mathrm{Y}$ are well defined sets
$X=\left\{x: x>0, x^{2} < 0\right\}$
We know that the square of each number greater thar zero is always greater than zero. So, X contains member and so, $\mathrm{X}$ is null set but a well defined set Also, $\mathrm{Y}=\{$ flower, Churchill, Moon, Kargil\} is wel
defined. So, Y is also a well defined set
