Answer
The molten component consists ONLY of CRYOLITE.
Explanation
The extraction of aluminium using electrolysis involves several factors and components including the anode, carbon, CO2, and cryolite. From the choices provided, the potential false statement should have an error in describing either the materials used or the products produced.1. It is correct that The ANODE is made of carbon. 2. CO2 is indeed a product of the reaction due to the burning of carbon anodes. 3. Cryolite is used in the electrolysis of containment of molten aluminium, where it reduces the melting point and thus aids in energy conservation. However, the statement "The molten component consists ONLY of CRYOLITE" is incorrect. Molten aluminium overall contains alumina (aluminium oxide), along with cryolite.
