Answer: The correct option is B. Vertebrates appeared in the oceans before they moved on to land.

Vertebrate paleontology involves study of fossils of the vertebrates starting from the earliest fishes to the ancestors of modern day mammals. The spreading up of life from water to land needed modifications and adaptations such as protection from drying and support against the gravity.
