Solution

The correct option is C Assertion is correct but Reason is incorrect
Sodium chloride is added during electrolysis of fused anhydrous magnesium chloride. As It lowers the fusion temperature of $M g C l_{2}$ and provide conductivity to the electrolyte.

And also, on direct heating of $M g C l_{2} .6 H_{2} O$ , anhydrous $M g C l_{2}$ is not obtained due to its hydrolysis so hydrated $M g C l_{2}$ is heated in vacuum in current of dry $H C l$ gas and $M g C l_{2}$ is formed.

Option C is correct.
