Which of the following terms describes a stationary front?

A stationary front is characterized by its position in the atmosphere; it does not move significantly over time, often remaining in the same place for an extended period. This stagnation typically leads to prolonged weather conditions in the area where the stationary front exists, such as cloud cover and precipitation. Unlike rapidly moving fronts, stationary fronts form when warm and cold air masses meet, but neither is strong enough to displace the other, thus leading to stability in their location. This phenomenon can have notable weather impacts, contrary to the idea that it causes no weather effects, and it can feature a mix of warm and cold air characteristics rather than being strictly cold. Therefore, the description that best captures the essence of a stationary front is one that highlights its position and duration of stability.
