Explanation:

If a scientific experiment is repeatedly giving you the same results that would mean that the results are precise and are very "reliable" for your conclusion which means your answer is the second option. During a experiment you are suppose to repeat the steps at least three times to make sure your results are reliable, doing so and it giving you the same results each trial just means that the results itself are very reliable.
