Thin layer chromatography of a mixture shows the following observation:
The correct order of elution in the silica gel column chromatography is

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

Which of the following statements is incorrect for paper chromatography?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Thin layer chromatography is an adsorption chromatography.
Reason $R$: $A$ thin layer of silica gel is spread over a glass plate of suitable size in thin layer chromatography which acts as an adsorbent.
In the light of the above statements,choose the correct answer from the options given below.
