Based on the figu A. Movement of solvent molecules will take place from chamber A to B.

B. Movement of solute will take place from A to B.

C. Presence of a semipermeable is a pre-requisite for this process to occur.

D. The direction and rate of osmosis depends on both the pressure gradient and concentration gradient.

Both the solution A and Solution B are separated by a semi-permeable membrane. The solute concentration is less in Solution A so the water potential is more in Solution A. So the movement of solvent molecules occurs from more dilute to less dilute solutioni.e the solvent molecules and not the solute molecules will flow from solution A to solution B. The solute particles wouldn't pass through the semi-permeable membrane.
