Which of the following occurs in this system?

A. Water does not cross the membrane at all. Water flows equally in both directions.

B. There is a net flow of water from the 10% starch solution into the 4% starch solution.

C. There is a net flow of water from the 4% starch solution into the 10% starch solution.

D. Starch moves out of the 10% starch solution into the 4% starch solution.

Hence option C is correct.

Explanation:

the process is osmosis a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.

so the answer for the this question will be There is a net flow of water from the 4% starch solution into the 10% starch solution because solvent (water) moving from low conc. (4 %) to high conc. (10%)

Hence option C is correct.
