Explanation
The correct answer is D because of the principle of buoyancy. Clouds are composed of tiny water droplets or ice crystals that are extremely small and light. These particles are spread out over a large volume of air, making the overall density of the cloud lower than the surrounding air. Because they are less dense, the upward force exerted by the air prevents them from falling quickly. Additionally, rising warm air currents known as updrafts help counteract the minimal weight of these low density particles, allowing clouds to remain suspended in the atmosphere.
