Solution

The correct options are
A At anode: $2 C l^{-} \to C l_{2} (g) + 2 e^{-}$
D At cathode: $C u^{2 +} + 2 e^{-} \to C u (s)$
The process of chemical change taking place in an electrolyte by passing electricity is known as electrolysis. Here the oxidation occurs at the anode and reduction at the cathode.

Following reactions take place during the electrolysis of $C u C l_{2}$ :

At anode: $2 C l^{-} \to C l_{2} (g) + 2 e^{-}$ (Oxidation)

At cathode: $C u^{2 +} + 2 e^{-} \to C u (s)$ (Reduction)
