Answer:
D. Performing experiments that have never been done before
Explanation:
A.P.E.X.
Performing experiments that have never been done before is most likely to lead to improving a scientific theory. The correct option is D.
A theory is a well-thought-out elaboration for natural-world observational data that has been built using the scientific process and incorporates many facts and hypotheses.
A theory not only helps to explain established information; it also allows scientists to predict what they will see if the hypothesis is correct.
Scientific theories can be tested. Emerging data should be consistent with an existing theory.
To improve a scientific theory, conduct novel experiments on it. This will provide greater clarity on the theory.
It may reveal the limitations of this theory, as well as aspects of the theory that can be improved.
Thus, the correct option is D.
