Solution
The correct option is C Flow of solution is not possible through semipermeable membrane Osmosis is defined as the flow of solvent molecules from a region of their higher concentration to a region of their lower concentration across a semipermeable membrane. Osmosis does not explains movement of solute particles or solution.
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
