(i) water will move from the side (A) to side (B) if a pressure lower than the osmotic pressure is applied on piston (B).

(ii) water will move from the side (B) to side (A) if a pressure greater than the osmotic pressure is applied on piston (B).

(iii) water will move from the side (B) to side (A) if a pressure equal to osmotic pressure is applied on piston (B).

(iv) water will move from the side (A) to side (B) if pressure equal to osmotic pressure is applied on the piston

Correct Answer: (ii) water will move from the side (B) to side (A) if a pressure greater than the osmotic pressure is applied on piston (B).

Explanation: If the pressure greater than the osmotic pressure is applied, then the water will move from side B to side A.
