You Have an Abundant Supply of NaCl Salt from Which

You have an abundant supply of NaCl salt from which you would like to prepare pure metallic sodium.

A) As the reduction potential of the aqueous Na⁺/Na couple is -1.662 V, this process is accomplished spontaneously in aqueous solution.
B) As the reduction potential of the aqueous Na⁺/Na couple is -1.662 V, this process is accomplished spontaneously from molten NaCl.
C) You prepare an aqueous solution of NaCl, apply a voltage of 1.662 V and collect metallic Na.
D) Na is produced by electrolysis of molten liquid NaCl at elevated temperature (NaCl mp. is 800^oC) .
E) Na is produced by electrolysis of solid NaCl.
