The reaction is a substitution reaction where iodine replaces the chlorine atom on the benzene ring. The major product will be the ortho isomer (IV) because it has the least steric hindrance due to the larger iodine atom being placed adjacent to the methyl group. The meta isomer (II) also has a comparable product yield, but the para isomer (III) is less likely due to the increased steric hindrance from the methyl group. Therefore, the best choice is IV.
