Solution
The correct option is C Sublimation
Ammonium chloride can be separated from sodium chloride by sublimation. It is the process in which a solid substance directly converts to vapour upon heating, without going through the liquid state.
On heating the mixture, ammonium chloride will sublimate and its vapours can be collected in a separate flask while sodium chloride will not vapourise and can be separated easily.
