The correct option is A
Copper Sulphate

Electrolytic refining is the method used to refine impure metals. In the process of electrolytic refining, a solution of the metal salt is used as an electrolyte. Since we need copper, we use a salt solution containing copper as an electrolyte. In this case, it is copper sulphate.
