Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
