Ineed with 57 and 58. you in advance

57. Answer is d. less concentrated since water passes from B to A.

Osmosis is the movement of water molecules from a region of higher water concentration to a region of lower water concentration. So water will move from B to A, making it less concentrated solution.

An important part to notice here is that its the movement of water molecules (or any other solvent) through the membrane and not the particles dissolved in the water.

58. Answer is a. It will rise in side A since water (not the substance in it) will tend to pass from the area of greater concentration to the area of lesser concentration.

i think the answer is b.
