Which Statement(s)is(are)NOT True for Partition and Adsorption Chromatography

Which statement(s) is(are) NOT true for partition and adsorption chromatography?
I For adsorption chromatography - the lower the eluent strength of the solvent,the more easily it displaces the solute.
II For partition chromatography - the more time the solute spends in the mobile phase,the easier it is to elute.
III For partition chromatography - solute equilibrates between the mobile phase and the liquid phase bonded to the solid support.
IV For adsorption chromatography - solvent molecules compete with solute molecules for binding sites on the stationary phase.

A) IV
B) I
C) III and IV
D) II
E) I and II
