Fossil steroid evidence indicates that animals may have originated around 710-770 million years ago, while molecular clock evidence suggests that they evolved more than 100 million years before the oldest known fossils of large animals. This supports the idea that animals originated before the Cambrian explosion, which occurred around 541 million years ago. Therefore, both choices A and B are correct.
