Mammals (Class Mammalia) are characterized by having a four-chambered heart, which allows for efficient separation of oxygenated and deoxygenated blood, facilitating a high metabolic rate. While birds (Aves) also have a four-chambered heart, reptiles generally have a three-chambered heart (except for crocodiles, which have a four-chambered heart), and amphibians have a three-chambered heart. An interesting fact about mammals is that they are the only vertebrates with hair on their bodies and the ability to produce milk through mammary glands to feed their young.

Introduction to Chordata and Heart Structure
The phylum Chordata encompasses a diverse range of animals, characterized by certain features such as a notochord, dorsal nerve cord, and gill slits at some developmental stage. Among these, different classes exhibit variations in their cardiovascular systems.
Three-Chambered Heart Overview
- A three-chambered heart consists of two atria and one ventricle.
- This structure is efficient for the physiological needs of many vertebrates, especially those living in varying environments.
Class Reptilia and Heart Structure
- The class Reptilia includes snakes, lizards, turtles, and crocodiles.
- Most reptiles possess a three-chambered heart, which aids in their adaptation to terrestrial life.
Comparison with Other Classes
- Amphibia: Also have a three-chambered heart, but they are distinct from reptiles.
- Mammalia: Characterized by a four-chambered heart, allowing for complete separation of oxygenated and deoxygenated blood.
- Aves: Birds also possess a four-chambered heart, similar to mammals, due to their high metabolic demands for flight.
Conclusion
While both Amphibia and Reptilia have three-chambered hearts, the question specifically asks for reptiles, as they are the main class in which this feature is prominent among terrestrial vertebrates. Thus, the correct answer is option 'D', Reptilia.
