A) from the 10% sucrose solution to the 20% sucrose solution
B) from the 20% sucrose solution to the 10% sucrose solution
C) There will be no diffusion in this case.
D) from the 10% sucrose solution to the 20% sucrose solution and from the 20% sucrose solution
E) neither from the 10% sucrose solution to the 20% sucrose solution nor from the 20% sucrose solution to the 10% sucrose solution

The net diffusion of sucrose will take place from the 20% sucrose solution to the 10% sucrose solution. This is because water molecules will move from the 10% sucrose solution to the 20% sucrose solution in order to equalize the concentration of the two solutions. As a result, the concentration of sucrose in the 20% solution will increase, leading to a net diffusion of sucrose from the higher concentration side (20%) to the lower concentration side (10%) until equilibrium is reached.
