$N$-Ethylphthalimide on hydrolysis gives:

An organic compound $A$ on reaction with $NH_{3}$ followed by heating gives compound $B$. Which on further strong heating gives compound $C$ $(C_{8}H_{5}NO_{2})$. Compound $C$ on sequential reaction with ethanolic $KOH$,alkyl chloride and hydrolysis with alkali gives a primary amine. The compound $A$ is.

The compound $A$ when treated with $HNO_3$ (in presence of $H_2SO_4$) gives compound $B$,which is then reduced with $Sn$ and $HCl$ to aniline. The compound $A$ is
