(b) benzoic acid
Explanation:
C6H5OH ---- Zn --> C6H6 ----- CH3Cl -- Anhydrous AlCl3----> C6H5CH3 ---- alkaline KMnO4 ---> C6H5COOH
Product Z is Benzoic acid.
Phenol in the presence of zinc yields benzene which reacts with chloroform and anhydrous AlCl3 to form Toluene. Toluene reacts with alkaline KMnO4 to yield benzoic acid.
Hence, option B is the correct answer.
