I have been asked this question in a national level competition.

I'd like to ask this question from Operation of Chromatography in division Chromatography of Analytical Instrumentation

Answer 1

Correct option is (a) Components of the sample

For explanation I would say: Chromatogram is a detector that responds to concentration solute and is placed at the end of the column. The position of peaks on the time axis can be used to determine components of the sample.
