Solution

The correct option is D $R C O N H_{2}$
In Hoffmann bromamide reaction, primary amide reacts with bromine and sodium hydroxide to form isocyanate, which is hydrolysed to give primary amine (with one carbon less) along with decarboxylation.
$R C O N H_{2} + B r_{2} + N a O H \to R - N = C = O H_{2} O \to - C O_{2} R N H_{2}$
