Which statement correctly describes how analytes are retained on different stationary phases in liquid chromatography?(A) In reversed-phase LC, hydrophobic stationary phases attract polar analytes through strong dipole-dipole interactions.(B) In normal-phase LC, analytes with higher polarity exhibit stronger retention because they interact more strongly with the polar stationary phase.(C) In ion-exchange chromatography, retention is dominated primarily by hydrophobic interactions between analytes and the stationary phase.(D) In size-exclusion chromatography, smaller analytes elute before larger ones because they cannot enter the pores of the stationary material.
