On which principle does the solute move on chromatography paper?

The correct match between Item $I$ and Item $II$ is

Item $I$	Item $II$
$a$. Benzaldehyde	$p$. Mobile phase
$b$. Alumina	$q$. Adsorbent
$c$. Acetonitrile	$r$. Adsorbate

Match Column-$I$ and Column-$II$ with the correct relation:

Column-$I$	Column-$II$
$(i)$ Aniline + chloroform	$(p)$ Steam distillation
$(ii)$ Aqueous solution of compound	$(q)$ Fractional distillation
$(iii)$ Mixture of liquids with small difference in boiling point	$(r)$ Differential extraction
$(iv)$ Purification of aniline	$(s)$ Simple distillation

The boiling point of aniline is $457 \ K$. At which temperature does aniline boil in simple distillation and in steam distillation?

Given below are two statements:
Statement $I$: Vapours of the liquid with higher boiling point condense before vapours of the liquid with lower boiling points in fractional distillation.
Statement $II$: The vapours rising up in the fractionating column become richer in high boiling component of the mixture.
