Solution

The correct option is D ethylene glycol
Colligative properties :- Those physical properties of a solution which depend upon the number of particles in a given volume of the solution or the mole fraction of the solute are called colligative properties.
The following four properties are colligative properties :
(i)Lowering of vapour pressure of the solvent.
(ii)Osmotic pressure.
(iii)Elevation in boiling point of the solvent.
(iv)Depression in freezing point of solvent.
Due to these properties, ethylene glycol is used as an anti-freezing agent in the radiator of car.
