Electrolytic reduction cell used for conversion of calcined Al2O3to Al is a carbon lined furnace operating at 800-900 °C. The purpose of electric current supplied to the furnace is to
(A) Achieve very high purity of aluminium (99.9%)
(B) Keep the electrolyte in liquid condition by the generation of heat (C) Electrolytically dissociate alumina
(D) Both (B) & (C)
