Answer: Option A.
Pure solvent diffused through a membrane but solutes do not.
Explanation:
Osmosis is process where solvents or molecules move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane which tend to balance the concentration of solutes. Osmosis is passive transport i.e it does not require energy for movement.
