Which of the following items is the best example of a system?
a. a tooth
b. claws
c. a hampster
d. fur

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

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 .
