In the context of passive transport (diffusion and osmosis), facilitated diffusion is best described as which of the following?
A
A passive process in which water moves through aquaporins from lower to higher solute concentration, carrying solutes with it
B

D
An active process that uses ATP to pump solutes against their concentration gradient through carrier proteins
