Answer:
The correct answer to the question is
The unknown solution had a higher concentration of solutes
Explanation:
The process of the movement of the molecules of the solvent across the semipermeable membrane is known as osmosis
Osmosis is the passive transport of a solvent such as water through a selectively permeable membrane in a direction from a region of low solute concentration to a higher concentration region so as to equalize the concentration of the solute on both sides of the membrane
