(C) $1$. The reaction of ethyl bromide $(C_2H_5Br)$ with $KCN$ is a nucleophilic substitution reaction.$2$. $C_2H_5Br + KCN \rightarrow C_2H_5CN + KBr$. Here,$A$ is ethyl cyanide $(C_2H_5CN)$.$3$. The hydrolysis of alkyl cyanides $(R-CN)$ yields carboxylic acids $(R-COOH)$.$4$. $C_2H_5CN + 2H_2O \xrightarrow{H^+} C_2H_5COOH + NH_3$.$5$. The product $B$ is propionic acid $(C_2H_5COOH)$.
