Question

Which of the following is the most important part of chordate?

• A. Hermichordate
• B. Vertebrata
• C. Mollusca
• D. All of the above

Answer 1

The correct option is B Vertebrata

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.

So, the correct answer is option B.
