Answer 1

The correct answer is (d) Bats are the only mammals that lay eggs and feed their young ones with milk

The best I can explain: Mammals are mostly terrestrial and feed their young ones with milk. Scales are absent, instead hairs, sweat and oil glands on skin. They respire through lungs and their heart is four-chambered. Platypus is the only mammal that lays eggs and feed its young ones with milk.
