Which of the following is a feature of a cold front?

A cold front is characterized by the leading edge of a cooler mass of air displacing a warmer mass. As the cold air advances, it forces the warm air to rise. This rising warm air can lead to the development of cumulonimbus clouds, which are often associated with thunderstorms. The nature of a cold front typically results in heavy rainfall as the warm moist air cools rapidly, leading to condensation and precipitation.

After the passage of a cold front, it is common to experience a drop in temperature, hence the cooler temperatures mentioned in the correct choice. The transition from warm, humid weather to cooler, drier air is a hallmark of a cold front's influence on the local weather.

The other choices reflect characteristics that are not typical of cold fronts. For instance, slowly rising warm air (mentioned in the first option) aligns more with warm front behavior. Rapidly moving warm air, as described in the second choice, does not accurately depict the dynamics of a cold front since it involves the movement of colder air. Lastly, stable weather conditions are often associated with high-pressure systems or warm fronts rather than the often turbulent weather conditions that are linked to cold fronts. Thus, heavy rainfall followed by cooler temperatures accurately encapsulates the defining features of a
