Correct Answer: I and II

Solution : The correct option is I and II

Sublimation is a change in which a substance transitions directly from a solid to a gaseous state, bypassing the intermediate liquid phase. It occurs when the prevailing temperature and pressure conditions allow the substance's vapour pressure to surpass that of its solid form. As a result, the molecules shift from a closely packed solid structure to a dispersed gaseous state without an interim liquid phase.
