The correct answer is:

C. Suspended particles provide a surface on which water droplets can form.

In the atmosphere, tiny suspended particles (also known as aerosols) serve as cloud condensation nuclei, which are essential for the formation of clouds. Water vapor condenses onto these particles to form droplets, leading to cloud formation.
