c. Filter.
Explanation:
Solubility is a term used to describe how readily a substance can be dissolved in a solvent to form a solution. Thus, a substance is said to be soluble if it dissolves completely in a solvent and insoluble if it doesn't dissolve or only dissolves partially.
Furthermore, a compound that dissolves completely in water to produce an aqueous solution is said to be soluble in water.
Basically, solubility is simply the amount of a substance such as salt, that will dissolve in a given amount of solvent. A solvent is any liquid such as water, coffee, tea, etc., that dissolves a liquid, gaseous, or solid solute to produce a solution.
Recrystallization is also referred to as fractional crystallization and it can be defined as a separation technique used for purifying an impure compound or chemical by dissolving it in an appropriate solvent. Subsequently, the desired compound or chemical can then be removed from the solution while leaving the residue (impurities) behind.
The complete steps in the process of recrystallization are;
A. Dissolve a substance in a minimal amount of hot solvent.
b. Allow the solvent to cool, precipitating the substances while impurities remain in solution.
c. Filter the mixture to collect the pure substance.
a. Dissolve a substance in a minimal amount of hot solvent.

c. Filter the mixture to collect the pure substance.
Solubility can be defined as a state in which a substance dissolves in a solvent to form a solution
In order words, it is the ability of a substance to dissolve in a solvent to form a solution.
An insoluble substance cannot dissolve in solvent to form solution.
