Solution

The correct option is A ${C H C l}_{3}$
It is given that the product has a very bad smell.
So, we can guess that the product may be an isocyanide and carbylamine reaction must be occurring.

So, $X$ must be chloroform( $C H C l_{3}$ )

The reaction is as follows:

$P h N H_{2} + C H C l_{3} + K O H \to P h N C$

$P h N C$ is foul smelling.
