If an experiment gives about the same result every time it is performed then its results are A. precise. B. accurate. C. reproducible. D. all of these?

If an experiment gives about the same result every time it is performed, its results are A. precise. Precision refers to the consistency of results across multiple trials. While accuracy pertains to how close the results are to the true value, reproducibility relates to the ability of the experiment to yield the same results under the same conditions. Therefore, the correct answer is A. precise.
