Answer 1

The end product C is ethyl alcohol.
$C H_{3} B r \to K C N A C H_{3} - CN \to H_{3} O^{+} B C H_{3} - COO H \to L i A l H_{4} C C H_{3} - C H_{2} - O H$
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.

Answer 2

The end product C is ethyl alcohol.

C H_{3} B r \to K C N A C H_{3} - CN \to H_{3} O^{+} B C H_{3} - COO H \to L i A l H_{4} C C H_{3} - C H_{2} - O H
