Answer:
The correct answer is B. No jaws. The new species resembles an ostrachodermi.
Explanation:
Ostrachodermi is an extinct class of agnate fishes, considered as the most ancient vertebrate. They were little filtering organisms, with no mandible or jaws, and no paired fins. Their bodies were covered by squama, bony plates, and shields. They used to move in the bottoms when they were feeding on detritus.
They can also merge in what’s known as an occluded front, an important stage in the development of many of the great weather-making low-pressure systems known as midlatitude cyclones.
I think the answer your looking for is smooth muscles and cardiac muscles. They only muscles that can be voluntarily controlled is skeletal muscles. Let me know if this is what you're looking for:)
