Through random genetic mutations of a species over time, beings with unique characteristics emerged. Based on the suitability of the adaptation to the environment, the beings would either be able to successfully reproduce, or not, and perish. Successful adaptations would be passed down to children, resulting in the adaptations persisting at least in the short term.

The correct answer is B. A bony skeleton
Explanation:
In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
