B. dissolution>dryness>filtration>evaporation

C. filtration>sublimation>evaporation>dryness

D. dissolution>filtration>sublimation>evaporation

The correct answer is: A. sublimation → dissolution → filtration → evaporation

Explanation:

  • Ammonium chloride is separated first by sublimation.

  • The remaining mixture is treated with water so sodium chloride dissolves (dissolution).

  • Sand is removed by filtration.

  • Finally, sodium chloride is recovered by evaporation.
