Which property should a solvent used in crystallization possess?

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

List-$I$ (Technique)	List-$II$ (Application)
$A$. Distillation	$I$. Chloroform-Aniline
$B$. Fractional distillation	$II$. Separation of crude oil fractions
$C$. Steam distillation	$III$. Aniline-Water mixture
$D$. Distillation under reduced pressure	$IV$. Separation of glycerol from spent-lye

Choose the correct answer from the options given below:

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

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.

Given below are two statements:
Statement $I$: $A$ mixture of $C_{12}H_{22}O_{11}$ (sugar) and $NaCl$ can be separated by dissolving sugar in alcohol,due to differential solubility.
Statement $II$: Rose essence from rose petals is separated by steam distillation due to its high volatility and insolubility in $H_2O$.

Choose the statement that is true about $A$,$B$ and $C$ in the following separation scheme.
