Answer:
<em>The correct option is A) Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as the movement of molecules against a concentration gradient i.e from an area of lower concentration to an area of higher concentration.
Facilitated diffusion can be described as the movement of molecules guided by other molecules such as integral proteins. These kinds of movements are a type of passive transport as the molecules move along the concentration gradient from an area of higher concentration to an area of lower concentration.
