(A) In the process of electrolytic refining of copper:$1$. An impure copper rod is used as the anode (connected to the positive terminal of the battery).$2$. $A$ thin strip of pure copper is used as the cathode (connected to the negative terminal of the battery).$3$. An acidified copper sulfate $(CuSO_4)$ solution is used as the electrolyte.$4$. On passing electric current,pure copper from the anode dissolves into the electrolyte,and an equivalent amount of pure copper from the electrolyte deposits on the cathode.$5$. The impurities from the anode settle down at the bottom of the tank as 'anode mud'.$6$. Figure $A$ correctly depicts this setup with the anode connected to the positive terminal and the cathode to the negative terminal.

Which one of the following figures correctly describes the process of electrolytic refining?
