Answer:
A
Solution:
Hot Potassium permanganate oxidizes any alkyl side chain on benzene having benzylic hydrogen to –COOH.
Here, toluene (–CH₃ group) gets fully oxidized irrespective of chain length.
Thus, –CH₃ → –COOH giving Benzoic acid as the major product.
Other options (aldehyde, alcohol, phenol) are not final oxidation products under strong conditions.
