Electrolysis of `CuSO_(4)` can be represented by two half cell reactions these occuring at cathode and anode respectively as
At cathode `Cu^(2+)+2e^(-)rarrCu(s)`
At anode `Cu(s)rarrCu^(2+)+2e^(-)`
Here, Cu will deposit at cathode while copper will dissolved at anode. Hence, options a and b are the correct choices.
