Initially, product A is the reduction of nitrobenzene means it is an aniline. when A react with HNO_{2} it gives benzene diazonium chloride(B). And when B reacts with another aromatic ring (phenol) it's a coupling reaction so it gives azodye (p-Hydroxyazobenzene)

        A= Aniline                          B = benzene diazonium chloride                         C= p-Hydroxyazobenzene
