Which term describes the rear-most part of the body in many animals?

• A. Head
• B. Mouth
• C. Tail
• D. Eye

Answer: (C)

The rear-most part of the body in many animals is the tail. The tail marks the posterior end, opposite the head, and in many species it extends from the trunk and serves roles in balance, propulsion, or signaling. The head, mouth, and eyes are all structures located toward the front (the head), so they describe the anterior region rather than the rear. While some animals have reduced or absent tails, the term tail is the best descriptor for the rear-most part in many others.
