Collections of tiny water and/or ice particles in the air are known as clouds. Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals around tiny dust or pollen particles. These droplets or crystals gather together to form visible masses in the sky that we see as clouds.
So, the correct answer to your question is:
a. Clouds
Clouds play a crucial role in the Earth's atmosphere by affecting weather patterns and reflecting sunlight, among other functions. Lightning, on the other hand, is a sudden electrostatic discharge that occurs during thunderstorms, while wind is the movement of air in the atmosphere.
