Solution

The correct option is A Chlorine
Chlorine is manufactured by the electrolysis of $N a C l$ solution where $C l_{2}$ is evolved at the anode and $H_{2}$ at the cathode.
At anode anode and $H_{2}$ at the cathode.
At anode: $C l^{-} \to C l + e^{-}, C l + C l \to C l_{2} ↑$
At cathode: $N a^{+} + e^{-} \to N a .$
