Stationary phase is a finely divided solid adsorbent

(B) Partition chromatography is based on the continuous differential partitioning of components of a mixture between a stationary phase and a mobile phase. In partition chromatography,the stationary phase is typically a liquid held on a solid support,whereas in adsorption chromatography,the stationary phase is a finely divided solid adsorbent. Therefore,the statement that the stationary phase is a finely divided solid adsorbent is incorrect for partition chromatography.

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

List-$I$ (Separation of) List-$II$ (Separation Technique)

$A$. Aniline from aniline$-water$ mixture $I$. Simple distillation

$B$. Glycerol from spent$-lye$ in soap industry $II$. Fractional distillation

$C$. Different fractions of crude oil in petroleum industry $III$. Distillation at reduced pressure

$D$. Chloroform$-Aniline$ mixture $IV$. Steam distillation

Choose the correct answer from the options given below:
