In the equation 1 and 2 we can take about the atmospheric nature of Aluminium oxide.

• The reason for my conclusion is in both the equation. Aluminium oxide reacts with Sodium and chlorine and release the water molecule after reacting. Molten cryolite used as a solvent for molten aluminium reduces the melting point of aluminium and behave that electrolyte it is mixed with molten aluminium extraction of graphite rods are used as cathode and carbon running is used as.

$\fbox\colorbox{pink}{Answer- (b)}$

• Molten cryolite used as a solvent for molten alumina. It reduces the melting point of alumina and behave that electrolyte. It is mixed with molten alumina in the extraction of aluminium.
• Graphite rods are used as cathode and carbon running is used as anode
