When benzene reacts with methyl chloride in the presence of AlCl3 catalyst, it undergoes Friedel-Crafts alkylation reaction. In this reaction, a hydrogen atom from benzene is replaced by a methyl group (-CH3) from methyl chloride. This results in the formation of toluene, which is a derivative of benzene with a methyl group attached to it. Therefore, the correct answer is toluene.
