Correct answer: A. Sheep
- A. Sheep
- B. Spiny ant eater
- C. Duck bill platypus
- D. Kangaroo
Explanation
The correct answer is Sheep. Sheep are placental mammals, meaning they have a placenta that provides nutrients and oxygen to the developing fetus during pregnancy. This is characteristic of mammals in the class Eutheria. In contrast, the spiny ant eater and duck-billed platypus are monotremes, which lay eggs and do not have a placenta. Kangaroos are marsupials, and they give birth to underdeveloped young that continue to grow in a pouch instead of having a placenta.
