Solution
The correct option is B Sublimation
Solid ammonium chloride on heating gets converted to vapours, without going through a liquid state whereas common salt does not evaporate. This process involving change of physical state from solid to vapours directly, without going through liquid state is known as sublimation and can be used to separate a mixture of salt and ammonium chloride.
