Solution
The correct option is A Osmosis cannot occur through an impermeable membrane Osmosis occurs only through the semi-permeable membrane. Osmosis is a gradient dependent process, osmosis is different from diffusion as it is characterized by a semi-permeable membrane.
So, the correct answer is 'Osmosis cannot occur through an impermeable membrane'.
a. Osmotic pressure is the external pressure required to be applied so that there is no net movement of solvent across the membrane.
b. Reverse Osmosis is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable Reverse Osmosis Membrane.
c. In Osmosis when equilibrium is reached, then water stops flowing across the membrane
