In which direction will water molecules (the small blue spheres) move across the membrane in the illustration shown here?

Attached is the illustration mentioned above. I found it on the internet.

The water molecules will move from B to A.
This process is named osmosis. Osmosis, in this specific case, describes the movement of the water (a solvent) through a semi-permeable membrane that allows it to get across but restricts the passage of a solute. This movement is done in the same direction of the gradient, meaning that the tendency will be to promote a balance and equalise the water concentration.
