(B) The presence of a nitro group $( -NO_2 )$ in aromatic compounds like nitrobenzene can be detected using the $Mulliken$ and $Barker$ test. In this test,the nitro compound is reduced to a hydroxylamine $( -NHOH )$ using zinc dust and ammonium chloride. The resulting hydroxylamine then reduces Tollens' reagent to metallic silver,which confirms the presence of the nitro group.
