Solution
The correct option is B
Friedel craft alkylation is an electrophilic aromatic substitution reaction. It happens in presence of lewis acid. Here, benzene will act as nucleophile and attacks the electrophile.
Vinyl cations are less stable due to presence of positive charge on sp2 hybridised carbon. Hence, option (b) does not form a stable carbocation. Hence, it does not undergo friedel crafts reaction.
