Solution
The correct option is A 99.99%
During electrorefining, impure copper is purified by the means of an electrolytic cell. The pure copper metal is attached at cathode and the impure one at anode. When electricity is passed through the electrodes, the pure copper is deposited on cathode leaving behind impurity at anode. Copper thus obtained is 99.99% pure.
