Final Answer :
E
Explanation :
Amphibians are not mammals; they are a class of animals that includes frogs, toads, salamanders, and newts, which have life cycles that include both aquatic and terrestrial phases. Mammals, on the other hand, are warm-blooded vertebrates with hair or fur and which typically give birth to live young and nurse them with milk produced by mammary glands. Dogs, goats, dolphins, and opossums are all mammals.
