A
Copper metal
💡 Explanation:
For every copper ion discharged at the cathode, a copper ion is released into the solution at the anode. The sulphate and the hydroxyl ions remain as spectator ions. The total number of copper and sulphate ions remain constant throughout. Assuming that no evaporation takes place, the blue color of the copper sulphate is maintained throughout.
