Question

based on the picture, which order does the platypus belong in?
chordata
mammalia
monotremata
animalia

Explanation:

The taxonomic hierarchy in the image shows the platypus's classification. Monotremata is the order that includes the platypus (along with the echidna), as monotremes are egg - laying mammals. Chordata is a phylum, Mammalia is a class, and Animalia is a kingdom, so Monotremata is the correct order.

Answer:

B. Monotremata
