Answer
Soln:
Answer is (a) Movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane
Explanation:
Osmosis is a special type of diffusion in which water molecules move from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
Option b) Movement of solvent molecules from its higher concentration to lower concentration is called as diffusion.
