Solution
The correct option is D Sublimation
Iodine changes directly from solid to gaseous state on heating.
The gaseous form of Iodine can be cooled easily to get a pure solid. The remaining components of the mixture are salt and sand.
Salt is soluble in water and sand is a non-water soluble substance that can be separated by the process of filtration.
The insoluble sand remains in the filter paper while the filtrate contains the dissolved salt.
Option C is correct.
