Solution

The correct option is B $I = s p_{2} I I = K e k u l e I I I = e l e c t r o p h i l i c I V = a c e t y l c h l o r i d e$
Benzene has a planar structure. All carbon atoms in benzene are $s p^{2}$ hybridised being bonded to two other carbon atoms and one hydrogen atom. The ring structure of benzene was proposed by Kekule. It shows electrophillic substitution reactions due to electron rich character. It reacts with acetyl chloride in presence of aluminium chloride to form acetophenone and the reaction is known as acylation of benzene.
Hence, A is correct answer
