Answer: D. From low solute concentration to high solute concentration.
Step-by-step explanation:
Osmosis is a process of movement of the molecules of the solvent like water passing through a semipermeable membrane like plasma membrane from a low concentration of the solute to the more concentration of the solute. Osmosis is a kind of passive transport, as it requires energy to occur.
For example, the movement of water molecule across the plasma or cell membrane into a cell with a high concentration of solute.
