Show Solution

The Correct Option is A

Solution and Explanation

Step 1: Oxidation step.
KMnO\(_4\)/KOH oxidises the methyl group on benzene to -COOH, giving benzoic acid.

Step 2: Halogenation and director effect.
The -COOH group is a strong meta-director (deactivating EWG). Br\(_2\)/FeBr\(_3\) substitutes at the meta position, giving meta-bromobenzoic acid.
\[ \boxed{\text{meta-Bromobenzoic acid}} \]
