Paper chromatography is an example of"
Column chromatography
Adsorption chromatography
Partition chromatography
Thin layer Chromatography
Paper chromatography is an example of partition chromatography because in paper chromatography the components are separated on basis of the difference in solubility of sample components in the stationary or mobile phase while in adsorption chromatography separation of components is done based on the rate of adsorption of components on the stationary phase.
Thin-layer and column chromatographies are adsorption chromatography.
Therefore, Option(3) is correct.
