Answer:
The correct answer will be- repetition of the experiment to test the hypothesis
Explanation:
A scientific experiment is performed to test the hypothesis which checks whether the hypothesis is true or not true.
Testing the hypothesis is the key of the scientific investigation so the repetition of the experiments is done to check the validity of the hypothesis either by the same researcher who formulated the hypothesis or another researcher who check and verify the results.
Thus, the repetition of the experiment to test the hypothesis is the correct answer.
