B

(CH3)2NH(CH_{3})_{2}NH

C

CH3NH2CH_{3}NH_{2}

D

C6H5NH2C_{6}H_{5}NH_{2}

Answer

C6H5NH2C_{6}H_{5}NH_{2}

Explanation

Solution

C6H5NH2NaNO3HClC6H5N2ClH2OC_{6}H_{5}NH_{2}\underset{HCl}{\overset{\quad NaNO_{3}\quad}{\rightarrow}}C_{6}H_{5}N_{2}Cl\overset{\quad H_{2}O\quad}{\rightarrow} C6H5OH+N2+HClC_{6}H_{5}OH + N_{2} + HCl
