Solution

The correct option is A $C_{6} H_{5} {CH}_{2} {CONH}_{2}$
Hoffmann degradation method is for the preparation of primary amines by treating an amide with bromine in an aqueous or ethanolic solution of $N a O H$ . The amine thus formed will be having one carbon atom less than that present in the amide.
$P h C H_{2} C O N H_{2} + B r_{2} + 4 N a O H ⟶ P h C H_{2} N H_{2} + N a_{2} C O_{3} + 2 N a B r + 2 H_{2} O$
