Assertion : Benzene reacts with iodine monochloride in presence of anhyd. AlCl₃ to form iodobenzene.

Reason : Iodine monochloride reacts with anhyd. AlCl₃ to produce I⁺ which attacks the benzene ring.

• If both assertion and reason are true and reason is the correct explanation of assertion

• If both assertion and reason are true but reason is not the correct explanation of assertion.

• If assertion is true but reason is false.

• If both assertion and reason are false.
