Q. No.Given below are two statements:
| 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 colored components of inks migrate at different rates because paper selectively retains different components according to the difference in their partition between the two phases. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
