Hydrocarbons

Among the following, the reaction that proceeds through electrophilic substitution is:

A.Benzenediazonium chloride + $C u_{2} C l_{2}$ $\to$ chlorobenzene + $N_{2}$ (Sandmeyer reaction)
B.Benzene + $C l_{2}$ , $AlC l_{3}$ $\to$ chlorobenzene + HCl (Friedel–Crafts halogenation)✓
C.Benzene + $C l_{2}$ , UV light $\to$ benzene hexachloride (free-radical addition)
D.Benzyl alcohol + HCl, heat $\to$ benzyl chloride + $H_{2} O$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
