Solution

The correct option is A Assertion and reason both are correct statements and reason is correct explanation for assertion.

Ammonium chloride sublimes on heating, which means it converts directly from solid state to gaseous state. Hence, it can be separated from sand easily using sublimation method.

Hence, option (A) is the correct answer.
