Answer

Brief Explanations:

A stationary front occurs when a cold air - mass and a warm air - mass meet and neither is strong enough to move the other, as shown in Item A. An occluded front forms when a cold front overtakes a warm front, as depicted in Item B where the cold air is undercutting the warm air and pushing it upward.

Answer:

Item A shows a stationary front, and item B shows an occluded front.
