Consider the figure and mark the correct option.

Options

A. Water will move from side (A) to side (B) if a pressure lower than osmotic pressure is applied on piston (B)
B. Water will move from side (B) to side (A) if a pressure greater than osmotic pressure is applied on piston (B)
C. Water will move from side (B) to side (A) if a pressure equal to osmotic pressure is applied on piston (B)
D. Water will move from side (A) to side (B) if pressure equal to osmotic pressure is applied on piston (A)

Explanation

We know that, if a pressure higher than the osmotic pressure is applied on the solution, the solvent will flow from the solution into the pure solvent through the semi-permeable membrane. This process is called reverse osmosis.
Thus, in this case, water will move from side (B) to side (A) if a pressure greater than osmotic pressure is applied on piston (B).
