Aluminium is extracted from aluminium oxide using electrolysis.
Carbon dioxide is formed in this process.
Which equation shows the formation of carbon dioxide during the extraction of aluminium from aluminium oxide by electrolysis?

A

Al2(CO3)3→Al2O3+3CO2\mathrm{Al}_{2}\left(\mathrm{CO}_{3}\right)_{3} \rightarrow \mathrm{Al}_{2} \mathrm{O}_{3}+3 \mathrm{CO}_{2}

B

Al2O3+3CO→2Al+3CO2\mathrm{Al}_{2} \mathrm{O}_{3}+3 \mathrm{CO} \rightarrow 2 \mathrm{Al}+3 \mathrm{CO}_{2}

C

C+O2→CO2\mathrm{C}+\mathrm{O}_{2} \rightarrow \mathrm{CO}_{2}

D

C4++2O2−→CO2\mathrm{C}^{4+}+2 \mathrm{O}^{2-} \rightarrow \mathrm{CO}_{2}
