Answer:
Sodium Chloride is an ionic solid and has high melting and boiling points. So it can't change in vapour phase simply at gas pressure hence it cannot sublime. Ammonium chloride, solid and iodine undergo sublimation which on heating without coming within the liquid state directly converts during a gaseous state.
