Question

which two organisms have hair? rabbits & birds; sharks & ray finned fish; primates & rodents; birds & crocodiles (with a phylogenetic tree image showing various organisms)

Explanation:

Hair is a characteristic feature of mammals. Primates (e.g., apes, humans) and rodents (e.g., mice, rabbits) are both mammalian groups, so they have hair. Rabbits are mammals but birds are not; sharks/ray-finned fish are aquatic non-mammals; birds and crocodiles are non-mammalian vertebrates.

Answer:

C. Primates & Rodents
