First toluene undergoes side chain halogination to give compound A. In compound A - CCl3 group is meta directing so meta product B is formed. B on reaction with Zn/HCl gives meta bromo toluene (.C.) . <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-jh8yb1hkflck.png" />
