Solution

The correct option is A ethyl chloride with $K C N$
KCN will provide one carbon to propane nitrile hence, starting material will have two carbon atoms.

$C_{2} H_{5} C l + K C N \to C_{2} H_{5} C N + K C l$

By reaction of $K C N$ with ethylchloride, propane nitrile forms as major product.

Option D is correct.
