Liquid-liquid chromatography employs liquid mobile and stationary phases. The principle of liquid-liquid separation is to partition solutes between two immiscible liquid phases. One phase is the mobile carrier and the other is the thin liquid layer supported on the inert stationary phase packed inside the column.
So, the correct answer is 'Both A and B'

Assertion :Chromatography in general involves a mobile phase (a gas, a liquid or a supercritical fluid) and a stationary phase (like Al2O3 column). Reason: A compound which is less soluble in the stationary phase takes longer time travel through it than a component which is more soluble in the stationary phase.
