Which of the following items is the best example of a system?

A. a tooth

B. claws

C. a hampster

D. fur

The correct answer is C.) A Hamster.

My reason being is because the Hamster has fur to keep it's organs warm, organs which include the lungs and etc, but to keep it simple, it's the claws fur a tooth well some teeth basically all of the above.

So the correct answer is C.) Hamster.

C a hampster because all the others are just parts of the system the hampster is the whole system.
