Solution

The correct option is C $K$ and $C l_{2}$
Carnallite is an ore of Potassium. $K C l . M g {C l}_{2} .6 H_{2} O$ .
Electrolysis of fused $K C l$ and $C a {C l}_{2}$ is carried out to obtain Potassium
$K C l ⇌ K^{+} + {C l}^{-}$
At Cathode: $K^{+} + e^{-} \to K$
At Anode: $2 {C l}^{-} \to {C l}_{2} + 2 e^{-}$
