Consider the Fig and mark the correct option.
1
water will move from side (A) to side (B) if a pressure lower than 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).
