Correct Answer - Option 3 : D

The correct answer is D.

  • ​Osmosis is a 'special diffusion process', which occurs through a semipermeable membrane.
  • In this, solvent molecules move from a low concentration solution to a high concentration solution.
  • This is a physical action.

  • Reverse osmosis is a technique of purifying water that uses a partially permeable membrane to separate ions, unwanted molecules, and larger particles from drinking water.
  • Capillarity – Capillarity is defined as a phenomenon of the rise or fall of a liquid surface in a small tube.
  • Viscosity - The fluid opposes the relative motion in its various layers, it is called viscosity.
