Answer:

C. Crocodile

• Most reptiles, belonging to the class Reptilia, exhibit a distinct characteristic in their circulatory system, specifically regarding their heart structure. Unlike mammals and birds which possess a four-chambered heart (two atria and two ventricles), most reptiles have a three-chambered heart. This means their heart consists of two atria (auricles) and a single ventricle that is incompletely divided.
