The answer is C because you need non running hamsters to compare running hamsters with.

Answer:

B

Explanation:

If you want to control the experiment, you want to make sure that no outside factor could potentially influence your results.

Hence, changing the diet of a hamster would significantly alter any results you may collect.

For example, if you allow hamster A to eat a nutritious diet, while not giving a proper diet to hamster B. Hamster A will perform better, and run further and for longer, because he has more energy.

The answer is B, because you want to make sure no hamster is at an advantage.
