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

Given below are two statements:
Statement-$I$: Retardation factor $(R_f)$ can be measured in $meter/centimeter$.
Statement-$II$: $R_f$ value of a compound remains constant in all solvents.
Choose the most appropriate answer from the options given below:

Identify the correct statements from the following:
$(i)$ Electromeric effect is a permanent effect.
$(ii)$ Hyperconjugation is a temporary effect.
$(iii)$ Fractional distillation is used to separate two liquids from a mixture if the difference in their boiling points is less.
$(iv)$ Different compounds are adsorbed on an adsorbent to different extents.

State whether the following statements are True or False:
$(i)$ The boiling points of chloroform and aniline are $334 \ K$ and $457 \ K$ respectively.
$(ii)$ The vapour of chloroform is obtained after aniline in simple distillation.
$(iii)$ Chloroform is more volatile than aniline.

The most suitable method of separation of a $1:1$ mixture of $ortho$- and $para$-nitrophenols is:

Match List-$I$ with List-$II$.

List-$I$ (Purification technique)	List-$II$ (Used to separate)
$A$. Simple distillation	$I$. Steam volatile compound
$B$. Fractional distillation	$II$. Two liquids with large difference in boiling points
$C$. Steam distillation	$III$. Liquid decomposing at its boiling point
$D$. Distillation under reduced pressure	$IV$. Two liquids with close boiling points
