Aliver cell requires energy to move vitamins from an area of low concentration, across the cell membrane, to an area of high concentration. this process used by the liver cell is called

Active Transport

Explanation:

Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.

In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
