Question

Vertebrata consist of which classes from the following?

• A. Bony fish
• B. Amphibians
• C. Reptiles
• D. All of the above

Answer 1

The correct option is D All of the above

Vertebrata is the most important part of chordate and is distinguished by a backbone (made either of bone or cartilage) having bones known as vertebrae and a skull enclosing a brain. The nervous system is entirely protected by these structures and also maintains the shape of the body.

The subphylum vertebrata is divided into seven classes: jawless fish, cartilaginous fish, bony fish, amphibians, reptiles, birds and mammals.

So, the correct answer is option D.
