Solution

The correct option is C Both a and b
Osmosis means diffusion of water across a differentially or semi-permeable membrane. The net direction and rate of osmosis depends on both the pressure gradient and concentration gradient. Water will move from its region of higher chemical potential (or concentration) to its region of lower chemical potential until equilibrium is reached.
