Hint: We have to know that the chromatography is used to separate different mixtures. There are two components in chromatography, one is stationary phase and other is mobile phase. As the name says, the stationary phase is the one in which the mobile phase passes over and the other is the mobile phase in which the fluid flows through the chromatographic system.
Complete answer:
We look at all the options to answer this question:
Option A) this is a correct option as partition chromatography is the chromatography in which the stationary phase is liquid and the mobile phase is also liquid. Thus it is also known as liquid-liquid chromatography.
Option B) This is an incorrect option as the stationary phase is not liquid. Also it is termed so as in it the solvent moves in a downward direction.
Option C) this is an incorrect option as the stationary phase in column chromatography is solid while the mobile phase in this is liquid, thus this option is incorrect.
Option D) this is an incorrect option as the stationary phase is the adsorbent in this type of chromatography whereas the mobile phase is either gas or liquid, thus this option is incorrect.
Note:
We have to know that chromatography can be of many types depending on the types of mixtures. The choice of stationary phase in chromatography depends upon the affinity toward the stationary phase. The components in the mixtures travel at different speeds thus the separation is based on the partition between mobile and stationary phase.
