(B) Paper chromatography is a technique based on partition chromatography,where the stationary phase is water trapped in the cellulose fibers of the paper and the mobile phase is a solvent. Option $B$ is incorrect because paper chromatography is a method or technique,not a stationary phase itself. The stationary phase is the water held by the paper,not the paper itself.

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

List-$I$ $(\text{Mixture})$ List-$II$ $(\text{Method of Separation})$

$A. CHCl_3 + C_6H_5NH_2$ $I. \text{Distillation under reduced pressure}$

$B. \text{Crude oil in petroleum industry}$ $II. \text{Steam distillation}$

$C. \text{Glycerol from spent-lye}$ $III. \text{Fractional distillation}$

$D. \text{Aniline-water}$ $IV. \text{Simple distillation}$

Choose the correct answer from the options given below:

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