Identify correct A , B and C in the reaction sequence given below :

Step-by-step solution

In first step nitration occurs by mixture of concentrated nitric acid and concentrated sulphuric acid. From this step nitrobenzene (A) is produced. In next step chlorination of nitrobenzene occurs, nitro group is meta directing which orients the incoming electrophile at meta position which results in formation of compound (B). In last step, reduction occurs and nitro group is converted into amino group and produces compound (C).
