Solution

The correct option is D Both Assertion and Reason are incorrect
In the Electrolytic refining method, the impure metal is made to act as anode. A strip of same metal in pure form is used as cathode. They are put in a suitable electrolytic bath containing soluble salt of same metal. The more basic metal remains in the solution and less basic ones go to the anode mud.
Copper is refined using an electrolytic method, anode of impure copper and pure copper strips are taken as cathode in the acidified copper sulphate solution. Impurities from the blister copper deposit as anode mud.
