Answer:
C. Is it made of cells?
Step-by-step explanation:
According to the Cell Theory, all living things are made of cells. Therefore, C is the right answer.
A is incorrect. There are nonliving things that can still move. For example, cars are nonliving, but they are able to move.
B is incorrect. Although all living things do contain DNA, some viruses, which are not considered to be living organisms, also contain DNA. Therefore, only using this question will not accurately tell you if this specimen is living or nonliving.
D is incorrect. Many living things cannot make their own food. These organisms are called consumers.
Hope this helps!
