The main principle involved in column chromatography is adsorption of

the solutes of a solution through a stationary phase & separates the 

mixture into individual components. This is based on the affinity towards

the mobile phase & stationary phase.

\therefore option (4) is correct. 


Option 1)

Gravitational force

Option 2)

Capillary action

Option 3)

Differential absorption of the substances on the solid phase.

Option 4)

Differential adsorption of the substances on the solid phase.
