Alcohol.
Reason: in paper chromatography the mobile phase is the solvent that moves through the stationary paper (e.g., water, ethanol, methanol, hexane or mixtures). The paper is the stationary phase; air is not the mobile phase in paper chromatography (it would be for gas chromatography), and a plastic plate is neither the mobile phase nor the usual stationary phase.
