Solution

The correct option is B Isopropyl chloride
Friedel craft reaction is carried out by the generation of a carbocation but in chlorobenzene, bromobenzene, chloroethene, lone pair of halogen are delocalized with π bonds to attain double bond character. So isopropyl chloride can be used as the halide component for Friedel-Crafts reaction.

Hence option B is correct.
