The electrolytic reduction of nitrobenzene in strongly acidic medium produces:

Step-by-step solution

The electrolytic reduction of nitrobenzene in an acidic medium gives phenyl hydroxyl amine. Since the medium is acidic so phenyl hydroxylamine undergoes rearrangement reaction and gives p-aminophenol. Thus, under a strongly acidic medium, nitrobenzene on electrolytic reduction gives p-aminophenol.
