(C) The conversion of $O$-acylated phenol to $C$-acylated phenol in the presence of a Lewis acid like $AlCl_3$ is known as the Fries rearrangement.In this reaction,the acyl group $(RCO-)$ migrates from the oxygen atom of the phenolic ester to the ortho or para position of the benzene ring.Since the atoms or groups within the molecule rearrange to form a new isomer,this process is classified as a molecular rearrangement reaction.
