Solution
The correct option is B Sublimation
The process in which a substance goes directly from solid state to gaseous state is called sublimation.
Ammonium chloride undergoes sublimation while salt does not. Hence, on heating the mixture, ammonium chloride will convert into vapours leaving behind salt. The vapours of ammonium chloride can be collected seperately.
