Solution

The correct option is A m-bromotoluene
In the first step, Toluene undergoes side-chain halogenation to give Benzotrichloride which is compound A. In the second step, benzotrichloride reacts with bromine in presence of Fe to give m-bromobenzotrichloride, which is compound B. And in the final step compound, B undergoes reduction with Zn and HCl to give the final product C as m-bromotoluene.
