Correct Option: C
An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas. The liquid or solid particles have diameter mostly smaller than 1 µm. They remain suspended in air for longer periods of time are transported to distances by winds. The finer particles could also be more easily re-suspended by subsequent wind action.
