ANSWER: C
The first step of the reaction involves the addition of a nitro group to the toluene. Because ‘R’ groups (such as CH3) are ortho/para directors, the nitro group will either be in an ortho or para position, in relation to the CH3. The next step involves oxidation of the toluene to become benzoic acid. Hence, C is the answer.
