Solution
The correct option is C Sublimation
Ammonium chloride is a sublimable substance, i.e., it changes directly from solid to gaseous state on heating while common salt (sodium chloride) is a non-sublimable substance. Therefore, sublimation technique can be used for separating the mixture of ammonium chloride and common salt.
Hence, the correct answer is option (c).
