Answer: D
A stationary front occurs when air flow on both sides of the front is neither towards the cold air mass nor towards the warm air mass.
At a stationary front the boundary between two air masses does not move: the winds on both sides blow roughly parallel to the front, so neither air mass advances.
The other options describe moving fronts. Warm air taking over territory held by cooler air is a warm front. Cold polar air actively advancing into warm air is a cold front. A cold front overtaking a warm front forms an occluded front.
