The monotreme examples listed are which animals?

Explanation:
Monotremes are a small, primitive group of egg-laying mammals. Among living mammals, the only ones that lay eggs are the platypus and the echidna. They represent an early-diverging lineage and share features like laying eggs and producing milk without nipples. The other animals listed belong to different mammal groups—anteaters are placental mammals, while kangaroos and koalas are marsupials. Therefore, the pair that shows monotremes is platypus and echidna.
