D Correct answer
Explanation

Tachyglossus refers to the echidna (spiny anteater), a monotreme mammal that indeed lacks teeth. Adult echidnas have no teeth - they use their long, sticky tongues to catch ants and termites. Whales, flying squirrels, and oryctoropus (likely a misspelling of a rodent) all have teeth at some life stage.
