Assertion (A): Components of a mixture of red and blue inks can be separated by distributing the components between stationary and mobile phases in paper chromatography.
Reason (R): The coloured components of inks migrate at different rates because paper selectively retains different components according to the difference in their partition between the two phases.

The correct option is D Both A and R are correct and R is the correct explanation of A.
Analyzing the assertion :
Paper chromatography is a type of partition chromatography. In paper chromatography, a special quality paper known as chromatography paper is used. Chromatography paper contains water trapped in it, which acts as the stationary phase. A strip of chromatography paper spotted at the base with ink is suspended in a suitable solvent.
This Solvent acts as the mobile phase. As the mobile phase starts moving on the paper, it will lead to the separation of red and blue inks.
So, the given assertion is correct.
Analyzing the reason :
The solvent rises up the paper by capillary action and flows over the spot. The paper selectively retains different components according to their differing partition in the two phases. So, the coloured components of ink will migrate at different rates and are separated.
So, the reason is also correct.
Therefore, both assertion and reason are correct, and reason is the correct explanation of assertion.
So, option (A) is the correct answer.
Both A and R are correct and R is the correct explanation of A.
