Statement I is correct: Amphibians have a three-chambered heart (two auricles and one ventricle) and are oviparous . Reptiles usually have a three-chambered heart and are oviparous . Statement II is incorrect: While it is true that crocodiles possess a four-chambered heart , they are reptiles and thus are oviparous, not viviparous. The text states reptiles are oviparous and does not list crocodiles as an exception to this reproductive mode .
