  Given below are two statements:
  Statement I: Benzendiazonium salt is prepared by the reaction of aniline with nitrous acid at 273-278 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 benzendiazonium salt with KI.
  In the light of the above statements, choose the most appropriate answer from the options given below:

  • Both Statement I and Statement II are incorrect.
    
  • Statement I is correct but Statement II is incorrect.
    
  • Statement I is incorrect but Statement II is correct.
    
  • Both Statement I and Statement II are correct.
