When an aqueous solution of `LiCl` is electrolyzed using graphite electrodes, as the current flows, the `pH` of the solution around cathode `……………………`
A. `CI_(2)` is liberated at the anode
B. `Li` is deposited at the cathode
C. as the current flow, `pH` of the solution around the cathode remains constant
D. as the current flows, `pH` of the solution around the cathode decreases
