The correct answer is option B.
The liquid or gas that carries the sample across the solid support is called mobile phase.
In chromatography, there are two phases: mobile phase and solid phase.
The mobile phase can be either in gas form or liquid form.
While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.
In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.
