The air becomes saturated when the capacity of containing moisture is full. At this point, air becomes incapable of holding any moisture. Condensation occurs and water vapour forms droplets in the form of clouds.

When air containing water reaches its saturation point, thena)no more ...
Explanation:
When air containing water reaches its saturation point, it means that the air is holding as much water vapor as it possibly can at a given temperature and pressure. At this point, the air is unable to hold any more moisture, resulting in the formation of visible water droplets or clouds.
What happens when air reaches its saturation point?
When air reaches its saturation point, the excess water vapor in the air begins to condense into tiny droplets. This process is known as condensation. The water droplets then gather together to form clouds.
Why does water vapor condense?
Water vapor condenses when the air becomes saturated because the air cannot hold any more water vapor. As the temperature drops or the air pressure increases, the air's capacity to hold moisture decreases, leading to condensation.
Formation of Clouds:
Clouds are formed when the air containing water vapor rises and cools. As the air rises, it expands and cools, causing the water vapor to condense into tiny droplets. These droplets then come together to form visible clouds.
Condensation and Droplet Formation:
The condensation process occurs when the water vapor molecules slow down and come closer together. This causes them to lose energy and form liquid water droplets. These droplets are suspended in the air and become visible as clouds.
Falling of Droplets:
The water droplets formed through condensation in the clouds eventually become too heavy to remain suspended in the air. Gravity pulls these droplets downward, causing them to fall as precipitation in the form of rain, snow, sleet, or hail.
Summary:
When air reaches its saturation point, excess water vapor condenses into tiny droplets, leading to the formation of clouds. These droplets eventually become too heavy and fall as precipitation. So, the correct answer is option 'C' - water vapor forms droplets.
