Consider the figure and mark the correct option.
                       

1. Water will move from the side (B) to side (A) if pressure is lower than the osmotic pressure is applied on piston (B).
2. Water will move from side (B) to side (A) if a pressure greater than osmotic pressure is applied on piston (B).
3. Water will move from side (B) to side (A) if a pressure equal to osmotic pressure is applied on piston (B).
4. Water will move from side (A) to side (B) if pressure equal to osmotic pressure is applied on piston (A).
