This question was posed to me in an internship interview.

I'm obligated to ask this question of Principles of Crystallization topic in chapter Crystallization of Food Processing Unit Operations

Answer 1

The correct option is (a) To purify chemicals

The best I can explain: Recrystallization is a technique used to purify chemicals. By dissolving both impurities and a compound in an appropriate solvent, either the desired component or impurities can be removed from the solution, parting the other behind.
