Solution

The correct option is D Assertion is correct but reason is wrong statement
Assertion:

Alkyl iodide can be prepared by reaction of arenes with iodine in the presence of an oxidising agent.

Halogenation reaction

So, the assertion is correct.

Reason:

$H I$ convert into $I_{2}$ by the oxidizing agent such as $H I O_{3}$ , although, $H I$ can convert aryl halides into arenes.

$5 H I + H I O_{3} \to 3 H_{2} O + 3 I_{2}$

So, the reason is incorrect.

Conclusion: Assertion is correct but reason is wrong statement.

Hence the correct option is c.
