Assertion: Potassium is not obtained by the the electrolysis of fused KCl
Reason: potassium vapourises at the melting point of KCl.

Options

A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
B. Both Assertion and Reason are true but Reason is not a correct explanation of Assertion
C. Assertion is true but Reason is false
D. Assertion is false but Reason is true
