from solution having lower concentration only
B
from solution having higher concentration only
C
from both sides of semipermeable membrane with equal flow rates
✓

✓

Answer

Correct option: D.

from both sides of semipermeable membrane with unequal flow rates.

d
Osmosis is the phenomenon of flow of pure solvent from the solvent to the solution or from a less concentrated solution to a more concentrated solution through a semipermeable membrane. Common semipermeable membranes are permeable to certain solute particles also. Infact, there is no perfect semipermeable membrane. Therefore we can say that flow of water through a semipermeable membrane takes place both sides with unequal rates.
