Sodium is made by the electrolysis of a ...

Sodium is made by the electrolysis of a molten mixture of about 40% NaCl and 60% `CaCl_2` because
(a)`Ca^(2+)` ion can reduce NaCl to Na
(b)`CaCl_2` helps in conduction of electricity
(c)this mixture has a lower melting point than NaCl
(d)`Ca^(2+)` can displace Na from`NaCl`.

A

`Ca^(++)` can displace Na from NaCl

B

This mixture has a lower meting point than NaCl

C

`CaCl_(2)` helps in conduction of electricity

D
