Using anhydrous `AlCl_(3)` as catalyst, which one of the following reactions produces ethylbenzene `(PhEt)` ?

Benzene undergoes both Friedel-Crafts alkylation and acylation reactions, with long n-alkyl chains, often rearranged products are obtained. Therefore, to prepare benzene derivatives with n-alkyl chains either Friedel-Crafts acylation or some other suitable method is employed. Using anhydrous AiCl, as catalyst, which one of the following reactions produces ethylbenzene (PhEt)?
