Question

Which of the following is a set of egg-laying mammals?

• A. Spiny ant eater and duck-billed platypus
• B. Spiny ant eater and opossum
• C. Spiny ant eater and scaly ant eater
• D. Opossum and kangaroo

Answer 1

The correct option is A Spiny ant eater and duck-billed platypus

Long-beaked echidnas are known as monotremes- a small and primitive order of mammals that lay eggs rather than give birth to live young.

There are only five living monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea.

So, the correct answer is option A.
