• C. The process of osmosis does not take place through a semi-permeable membrane.
• D. All of the above

Answer 1

The correct option is B

The process of osmosis takes place through a semi-permeable membrane.

Osmosis is the phenomenon of diffusion of solvent molecules across a semi-permeable membrane.A semi-permeable membrane allows only water molecules to pass through.The examples of a living semi-permeable membrane are fish bladder, egg membrane etc.The examples of an artificial semi-permeable membrane are parchment paper or cellophane.
