1. Both A and R are True
2. Both A and R are False
3. A is True and R is False.
4. A is False and R is True.

Assertion. Diffusion is the process of free movement of liquid molecules only. It does not occur in gaseous state.

Reason. The main condition which regulates the process of diffusion is the concentration gradient and not the state of matter. It always occurs from higher to lower concentration.
