Given below are two statements:
Statement I: Benzenediazonium salt is prepared by the reaction of aniline with nitrous acid at \(273-278~ \text{K}.\) It decomposes easily in the dry state
Statement II: Insertion of iodine into the benzene ring is difficult and hence iodobenzene is prepared through the reaction of benzenediazonium salt with \(KI.\)

In the light of the above statements, choose the most appropriate answer from the options given below:  
1. Statement I is correct; Statement II is incorrect
2. Statement I is incorrect; Statement II is correct
3. Both Statement I and Statement II are correct
4. Both Statement I and Statement II are incorrect
