Surface tension
B
Osmotic pressure
C
Viscosity
D
Refractive index
Answer
Osmotic pressure
Explanation
Solution
Colligative properties- The properties that depend upon the ratio of the number of solute molecules and total molecules not upon the nature of solute molecules named as colligative properties. Example- Osmotic pressure, elevation of boiling point, depression in freezing point and relative lowering of vapour pressure.
