Question

Which of the following is an oviparous mammal?

• A. platypus
• B. kangaroo
• C. flying fox
• D. blue whale

Answer 1

The correct option is A

platypus

Mammals are mostly viviparous, except certain lower groups such as the monotremes, which includes oviparous mammals. Platypus is an example. Kangaroo, flying fox (bat) and blue whale are viviparous mammals. Kangaroos however, are marsupials, and give birth to under-developed young ones which are nurtured within a pouch attached to the mother's body, until they are fully developed.
