Solution

The correct option is C $C_{2} H_{5} C N$
This is an example of nucleophilic substitution reaction $(S_{N} 2)$ in which the chloride ion is displaced with cyanide ion.

$C_{2} H_{5} C l + K C N C_{2} H_{5} O H ⟶ C_{2} H_{5} C N X + K C l$

Thus, the product $X$ is ethyl cyanide.

Ethyl chloride reacts with $K C N / N a C N$ and alkyl cyanide forms. But ethyl chloride reacts with $A g C N$ and isocyanide forms.

Option A is correct.
