D. a solute concentration gradient

Osmosis is the passive movement of water across a selectively (semi-)permeable membrane from the side with higher water (lower solute) concentration to the side with lower water (higher solute) concentration. It requires a solute concentration difference; it does not require an enzyme or necessarily a protein, and the membrane must be selectively permeable (not fully permeable).
