Solution

The correct option is A Ethyl alcohol
The end product C is ethyl alcohol.
$C H_{3} B r K C N \to C H_{3} - C N A H_{3} O^{+} \to C H_{3} - C O O H B L i A l H_{4} \to C H_{3} - C H_{2} - O H C$
Methyl bromide reacts with KCN to form acetonitrile. Br atom is replaced with CN group. Hydrolysis of cyano group gives carboxylic group. Reduction of carboxylic group gives hydroxyl group.
