The correct answer is B.Precipitation.

Explanation:

Precipitation occurs when clouds become too heavy with water and can no longer hold the moisture. As a result, the water falls back to Earth in the form of rain, snow, hail, or sleet, depending on the temperature.

1.Clouds form during condensation, when water vapor in the air cools and changes back into liquid droplets, but they only remain in the cloud if the water droplets are small enough to stay suspended.

2.As the droplets combine and grow larger, the cloud can no longer hold them, and they fall as precipitation.
