Best answer
The correct choice is (d) Friedel-Crafts Alkylation

The best I can explain: The reaction in which benzene reacts with alkyl halide in the presence of a lewis acid as a catalyst to produce alkylbenzene is known as Friedel-Crafts Alkylation. With anhydrous ferric chloride as a catalyst, the alkyl group attaches at the former site of the chloride ion.
