Answer 1

The correct option is (d) The necessary condition for being a mammal is to give birth to their young ones

The explanation: African elephant is the largest mammal on the Earth. Mammalia derives its origin from Latin word Mamma which means breast. Mammals have hair or fur and are warm-blooded. The necessary condition for being a mammal is to feed their young ones with milk. Although most animals reproduce by laying eggs there are few exceptions to this.
