Answer:
The correct answer is option D. "See which theory does a better job of explaining the results of the experiment".
Step-by-step explanation:
A theory is a well established supposition that explains a phenomenon observed in nature or in laboratory based on proved principles. A scientist could compare theories by doing an experiment to see which theory does a better job of explaining the results of the experiment. This helps to see which theory is accurate and getting closer to get a definitive explanation to the observed phenomenon.
