# Cryolite is

$(a)\;\text{used in the electrolysis of alumina for decreasing electrical conductivity } \\(b)\;\text{ used in the electrolysis of alumina for lowering the melting point of alumina} \\(c)\;\text{used in the electrolytic purification of alumina} \\ (d)\;\text{ used in the electrolysis of alumina }$

Cryolite is used in the electrolysis of alumina for lowering the melting point of alumina
Hence b is the correct answer.
