Ans B

During electrolysis of aqueous copper sulphate solution using platinum electrodes, the blue colour of the electrolytic solution fades and towards the end of the process bubbles appear at the cathode.

The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper. During electrolysis, the anode loses mass as copper dissolves, and the cathode gains mass as copper is deposited. A half-equation shows what happens at one of the electrodes during electrolysis.
