Answer:
B. A cold front pushes warm air upward, and the cold front collides with a cold front,
Explanation:
An occluded front is a form of a weather front that is formed in a situation or condition that involves a cold front surpassing a warm front. Here, the cold air mass from the cold front moves faster to collides with the cool air that is in front of the warm front. This will then lead to warm air rising when the air masses joined concurrently.
Hence, the best evidence to support that an occluded front is occurring is option B A cold front pushes warm air upward, and the cold front collides with a cold front,
