Hello!!
Your question is related to electrochemistry ,I assume that you know the concept of reduction potential,look reduction potential of copper is more than that of reduction potential of hydrogen so it will always get reduced thus there is no possibility of displacing hydrogen.
Thank you!!
Question : Electrolysis of an aqueous solution of copper sulphate using copper electrodes gives
Option 1: copper at the cathode, and oxygen at the anode
Option 2: copper at the anode, and oxygen at the cathode
Option 3: copper at the cathode, and anodes dissolve to give copper
Option 4: hydrogen at the cathode, and oxygen at the anode
