The saturation vapor pressure of moist air is defined as the pressure at which water vapor in the air is in equilibrium with its liquid or solid form. This happens when the air is holding the maximum amount of water vapor it can at a given temperature. When the air reaches this point, any additional water vapor added to the air will not result in an increase in the vapor pressure; instead, it will start to condense into liquid water or ice.

This concept illustrates that saturation occurs when the water vapor content cannot increase any further without resulting in condensation. At this stage, the air can hold no more moisture, indicating full saturation. Hence, the correct answer highlights this critical moment in the moisture capacity of the air.

Understanding saturation vapor pressure is essential for meteorology, particularly in predicting weather patterns, humidity levels, and cloud formation processes.
