A Correct answer
Explanation

Monotremes are a unique order of mammals that lay eggs instead of giving birth to live young. The platypus and echidna (spiny anteater) are the only living monotreme species, found only in Australia and New Guinea. This egg-laying characteristic is primitive among mammals, distinguishing them from marsupials and placental mammals.
