Solution
The correct option is C Amphibians
The fossil record provides evidence of the first tetrapod amphibian species that lived nearly 400 million years ago and have now become extinct. One of the earliest known tetrapods is from the genus Acanthostega. Its fossil indicates that it was aquatic and had gills similar to fishes. It had four limbs with the skeletal structure of limbs found in present-day tetrapods, including amphibians. Thus the correct answer is optionD.
