$A$. Glycerol is purified by vacuum distillation because it decomposes at its normal boiling point.
$B$. Aniline can be purified by steam distillation as aniline is miscible in water.
$C$. Ethanol can be separated from ethanol water mixture by azeotropic distillation because it forms azeotrope.
$D$. An organic compound is pure, if mixed $M.P$. is remained same.
