Molten $CuCl_2$ is electrolysed using platinum electrodes. The reaction occurring at the anode is:

• A
  $2 Cl^{-} \longrightarrow Cl_{2(g)} + 2 e^{-}$
• B
  $Cl_{2(g)} + 2 e^{-} \longrightarrow 2 Cl^{-}$
• C
  $Cu^{2+} + 2 e^{-} \longrightarrow Cu_{(s)}$
• D
  $Cu_{(s)} \longrightarrow Cu^{2+} + 2 e^{-}$
