In column chromatography, the moving phase consists

A) A substance which is to be separated

B) Adsorbate

C) Adsorbent

Column chromatography involves separation of a mixture over a column of adsorbent (stationary phase) packed in a glass tube.

A suitable eluent, either a single solvent or a mixture of solvents is allowed to flow down the column
slowly.
