The correct option is D A - iv, B - iii, C - i, D - ii
Nitrobenzene can be reduced by using various products.
The products of reduction depend on the reducing agent used.
Reduction of nitrobenzene with tin in presence of HCl gives aniline (aminobenzene).
$C_{6} H_{5} N O_{2} S n + H C l - ----- \to C_{6} H_{5} N H_{2}$

Reduction of nitrobenzene with zinc in presence of ammonium chloride gives phenyl hydroxyl amine.
$C_{6} H_{5} N O_{2} Z n + N H_{4} C l - ------- \to C_{6} H_{5} N H O H$

Reduction of nitrobenzene with lithium aluminum hydride gives azobenzene.
$C_{6} H_{5} N O_{2} Z n + N H_{4} C l - ------- \to C_{6} H_{5} - N = N - C_{6} H_{5}$

Reduction of nitrobenzene with zinc in the presence of alcoholic potassium hydroxide gives hydrazobenzene.
$C_{6} H_{5} N O_{2} Z n + K O H - ------ \to C_{6} H_{5} - H N - N H - C_{6} H_{5}$
