D. Continuous change of solvent polarity during elution. E. Continuous temperature change during elution.

Explanation / Answer

Answer is B.

Less polar stationary phase and more polar mobile phase.

That's why it is called reverse, as in normal chromatography we use highly polar silica or alumina as stationary phase
