Which of the following is/are the application(s) of chromatography?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → All of these
Chromatography separates substances that dissolve in the same solvent but move up a paper or column at different speeds. It is used to separate the colours in a dye, the pigments of natural colours (such as chlorophyll) and drugs from blood, so all three uses are correct.
