If a 10% sucrose solution is separated from a 20% sucrose solution by a membrane impermeable to sucrose, in which direction will net movement of water occur?

a) From the 10% sucrose solution to the 20% sucrose solution only
b) From the 20% sucrose solution to the 10% sucrose solution only
c) From the 10% sucrose solution to the 20% sucrose solution and from the 20% sucrose solution to the 10% sucrose solution
d) There will be no net movement of water in this case.
e) None of the answers are correct.
