Which purification technique is used for high boiling organic liquid compounds that decompose near their boiling point?

Compare the pressure of aniline and water in vapour phase distillation.

Which of the following statements are correct?
$A$. Glycerol is purified by vacuum distillation because it decomposes at its normal boiling point.
$B$. Aniline is purified by steam distillation as it is immiscible in water.
$C$. Ethanol can be separated from an ethanol-water mixture by azeotropic distillation because it forms an azeotrope.
$D$. An organic compound is pure if the mixed $M.P.$ remains the same.

Which purification method is used to separate liquids that have a sufficient difference in their boiling points?

How do you perform the purification of the following?
$(i)$ The boiling point of liquid $X$ is $450 \ K$ and it decomposes at $400 \ K$ temperature.
$(ii)$ Mixture of $60 \% \ \text{Camphor}$ and $40 \% \ BaSO_4$.

Match List-$I$ with List-$II$:

List-$I$ $(\text{Mixture})$	List-$II$ $(\text{Method of Separation})$
$A. CHCl_3 + C_6H_5NH_2$	$I. \text{Distillation under reduced pressure}$
$B. \text{Crude oil in petroleum industry}$	$II. \text{Steam distillation}$
$C. \text{Glycerol from spent-lye}$	$III. \text{Fractional distillation}$
$D. \text{Aniline-water}$	$IV. \text{Simple distillation}$
