    Answer:

    A.It lowers the melting point of alumina. B.It increases the electrical conductivity. … Hint: The solution of alumina and cryolite during the electrolysis gives the aluminium at cathode and oxygen at anode. The alumina is a poor conductor of electricity and the fusion temperature of alumina is about 2000∘C.
