Solution

The correct option is A aerosol.
An aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas. Aerosols can be natural or anthropogenic.

Colloidal solutions can be classified on the physical state of dispersed phase and dispersion medium. If the dispersion medium is air then the sol is called aerosol.

Hence,option A is correct.
