D. The theory has been conclusively proven within its particular realm.



Answer :

Final answer:

A scientific theory is open to testing and revision, scientists continuously refine theories through testing and peer review, and accepted theories are continuously assessed for validity.


Explanation:

A scientific theory undergoes constant testing and is subject to revision and refutation as new evidence arises. It is a well-tested explanation for a broad set of observations or phenomena.

Scientists never claim absolute knowledge of nature and acknowledge that a theory is always open to falsification with new evidence. The process of peer review and ongoing testing ensures the reliability of scientific theories.

After a theory is accepted, it is continuously tested against new data, and if it fails to explain or contradicts new evidence, it may be revised or rejected.
