Answer 2

Answer:

Sodium Chloride is an ionic solid and has high melting and boiling points. So it can not change in vapour phase simply at atmospheric pressure hence it cannot sublime.

Ammonium chloride, dry ice and iodine undergo sublimation which on heating without coming in the liquid state directly convert in a gaseous state.
