Answer: c. Many days of cloudy, wet weather
A stationary front develops a transition zone between the hot and cold air masses. A stationary front forms between the cold and warm front when these fronts does not move.This occurs when the two air masses pushes each other, and neither of the two is powerful enough to move the other. It results in no change in the weather conditions for many days. The weather conditions associated with stationary front are cloudy and rainy, especially if the stationary front is in the area of low atmospheric pressure.
Therefore, a stationary front would bring many days of cloudy and wet weather conditions.
