Dr. Harris believes that the fur thickness of a specific rabbit species is directly related to the outside temperature of the rabbit's habitat. Other scientists in his field believe that the fur thickness of this species of rabbit is actually determined by the amount of sunlight that the rabbit is exposed to daily.

Dr. Harris performs an experiment to test whether temperature or sunlight affects fur thickness in this species of rabbit. Which of the following is true about the results of Dr. Harris' experiment?
A.
The results of the experiment may reinforce or weaken either hypothesis.

B.
The results of the experiment must support and reinforce Dr. Harris' hypothesis.

C.
The results of the experiment must support and reinforce the opposing hypothesis.

D.
The results of the experiment may prove either hypothesis to be fact.
