Liquid chromatography can be performed in which of the following ways?

1.	Liquid chromatography can be performed in which of the following ways?(a) Only in columns(b) Only on plane surfaces(c) Either in columns or on plane surfaces(d) Neither in columns nor on plane surfacesThe question was posed to me during an online exam.Question is from Introduction to Chromatography in section Chromatography of Analytical Instrumentation
Answer» Correct ANSWER is (C) Either in COLUMNS or on plane surfaces To explain I would say: Liquid chromatography can be performed either in columns or on plane surfaces. It could be liquid-solid chromatography or liquid-liquid chromatography.
