b) Stationary fronts usually are associated with light precipitation and light cloud cover.
<h2>Explanation:</h2>
Stationary fronts occur due to a barrier dividing warm and cold air without one displacing the other. There is a slight movement of either the cold or warm air, moreover, at the barrier, fog and light clouds form seeding light rain or snow.
The stationary front may last for days unless the direction of the air changes causing the movement to either cause a cold or warm front or break the front. The boundary created by this phenomenon results in different temperatures and wind on either side of the front.
