Solution

The correct option is C
a) Benzene generally gives electrophilic substitution reactions. This reaction is Halogenation reaction but proceeds in presence of Lewis acid catalyst.

b) The lone pair on oxygen of $O - H$ in phenol is shared with benzene ring through resonance. So the lone pair is not fully present on oxygen. Hence phenols do not undergo protonation reactions. Hence, the reaction also doesn't occur.

c)

(d) The iodination reaction is reversible and the $H I$ so produced in the reaction is a very strong reducing agent which reduces iodobenzene back to benzene.

Hence, option C is correct.
