Active transport is best described by the following option:

It moves materials from low concentration to high concentration, and requires energy.

Active transport involves the movement of substances against their concentration gradient, which means moving from an area of lower concentration to an area of higher concentration, and this process requires energy, usually in the form of ATP.
