Answer:

Option-A

Explanation:

Chondricythes is a group of fish which can be characterized by its jawbones, presence of cartilage, and paired fins.

The natural events and phenomenon can be explained by a scientific method which begins with asking a question, background research and then predicting a statement which explains the natural event called a hypothesis.  A hypothesis must be supported by the evidence.

In the given question, the hypothesis explaining the evolution of the Chondricythes changed with time which shows that the hypothesis can be revised with the advancement in technology and the production of new evidence which could either favour or do not favour.

Thus, Option-A is correct.
