A Correct answer
Explanation

This option is correct because with the increase in size the magnitude of intermolecular Van der Waal forces increases, thus, the boiling point also increases. Because iodide ion is larger in size than chloride ion, HI has higher a boiling point than HCl and if a metal exhibits more than one oxidation state, the halides in higher oxidation state will be more covalent than the one in a lower oxidation state. For example: SnCl4, PbCl4, SbCl5 and UF6 are more covalent than SnCl2, PbCl2, SbCl3 and UF4 respectively.
