In the correct of the Hall-Heroult process for the extraction of `Al`, which of the following statements is false ?

`CO` and `CO_(2)` are produced in this process

`Al_(2)O_(3)` is mixed with `CaF_(2)` which lowers the melting point of the mixture and brings conductivity

`Al^(3+)` is reduced at the cathode to form `Al`

`Na_(3)AlF_(6)` serves as the electrolyte
