Which term identifies animals with hair and mammary glands?

Explanation:
Hair and mammary glands are hallmarks of mammals. Hair helps with insulation and protection, while mammary glands produce milk to feed the young, a defining reproductive trait of this group. Reptiles are characterized by scaled skin and egg-laying, birds by feathers and eggs, and fish by gills and fins; none of these traits define them in the same way as hair and milk production do for mammals. So, the term that identifies animals with hair and mammary glands is mammals.
