Answer:
Tert-butylbenzene has no benzyl hydrogen therefore, it will not give benzoic acid on reaction with potassium permanganate.
Therefore, the correct option is (4).
Explanation:
The reaction is given in the question, only those compounds will be converted into benzoic acid which has benzyl hydrogen.
Options 1, 2, and 3 have 3, 3, and 1 benzyl hydrogen respectively. But tert-butylbenzene does not have any benzyl hydrogen therefore, it can not be converted into benzoic acid.
Therefore, the correct option is (4).
