Best answer
Right choice is (d) Clouds are not a colloidal system

The explanation is: When it is cold, the moisture in the air condenses on the surface of dust particles, forming tiny droplets. These droplets are colloidal in nature and form a blanket of fog or mist in the atmosphere. Clouds are colloidal systems as they are aerosols consisting of water droplets suspended in air.
