Answer :
D is the correct answer because osmosis is the movement of a solvent ( mainly water ) from area of higher concentration to that of lower concentration through a semi-permeable membrane ..
Answer:
D. the process where a selectively permeable membrane allows the movement of water through it
Explanation:
Osmosis is the movement of water molecules through a selectively permeable membrane from the region of high water potential to the region of low water potential.
It can also be defined as the movement of water molecules through a selectively permeable membrane from the region of low solute concentration to the region of high solute concentration.
Hence, osmosis always involves the movement of water molecules through a selectively permeable membrane.
The correct option is D.
