Answer:
A. Cambrian explosion , Active plate margin, True.
Explanation:
- The burgess shale is a window into life on earth during the exposition of Canadian Rockies. Itis one of the earlier imprints containing the soft part imprints.
- Fossil deposits of burgess shale correlate to the Stephen formation. that were collected about 508 million years ago. Beds were deposited at the base of the cliffs 160 meters tall.

Answer:
c. At either plate boundaries or in the middle of plates
Explanation:

However, a few volcanoes can appear in the middle of the technical plates, through the hot spots, which can suggest well inside the plate.
I believe it is the third choice, there was nothing then a sudden explosion, creating the universe
