(A) The reaction of anisole $(C_6H_5OCH_3)$ with hydrogen iodide $(HI)$ involves the cleavage of the $C-O$ bond.Since the $C_6H_5-O$ bond has partial double bond character due to resonance,the $O-CH_3$ bond is cleaved.This results in the formation of phenol $(C_6H_5OH)$ and iodomethane $(CH_3I)$.The reaction is: $C_6H_5OCH_3 + HI \xrightarrow{\Delta} C_6H_5OH + CH_3I$.
