Which of the following does not undergo sublimation?

Sodium chloride does not undergo sublimation.
Sublimation is when a substance changes directly from the solid to the gas phase without passing through the intermediate liquid phase.

For example, iodine and ammonium chloride produce fumes on gentle heating, while sodium chloride does not sublimate.

Now, in the case of sodium chloride, the values of the boiling point and melting point are not close enough to bring about sublimation. For sublimation, we know that the melting point of the solid state and boiling point of the liquid state should be very close to each other.
