The correct answer is C. Reptiles.

Herpetology is the scientific study of reptiles and amphibians. The word “herpetology” comes from the Greek words “herpeton”, meaning “creeping thing”, and “logos”, meaning “study”. Herpetologists study the biology, ecology, evolution, and behavior of reptiles and amphibians. They also study the conservation and management of these animals.

Reptiles are a diverse group of animals that includes snakes, lizards, turtles, tortoises, crocodiles, and alligators. They are characterized by their scaly skin, which helps to protect them from predators. Reptiles are ectotherms, which means that they cannot regulate their own body temperature and must rely on external sources of heat, such as sunlight.

Amphibians are a group of animals that includes frogs, toads, salamanders, and caecilians. They are characterized by their moist skin, which helps them to breathe in water. Amphibians are also ectotherms.

Herpetology is a fascinating field of study that provides insights into the biology of these unique animals. Herpetologists play an important role in conservation and management of reptiles and amphibians.
