C. Both I and II
Step-by-step solution
Evaporation is a process in which the volatile solvent is vaporized, leaving the non-volatile solid solute behind. It is commonly used to separate dissolved solids from liquids, such as obtaining salt from seawater. Crystallization is a process where a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. It is used to separate a pure solid in the form of its crystals from a solution. Both evaporation and crystallization are effective methods for separating a non-volatile solid solute from a solution. Answer: Both I and II
