Solution

The correct option is B Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
When an electric current is passed through the copper sulphaate electrolyte, the impure copper anode gradually dissolves and pure copper is deposited on the cathode.because of The negative cathode electrode attracts Cu2+ ions (from copper sulfate)
the Electroplating techniques are extensively used for the depositionof pure-metal and alloy thin films
