To eliminate alternative explanations for the results of an experiment.

Explanation:

The scientific experiments include all the procedure and observations that are observed during the experiments. The scientific experiments explain about the correct scientific information.

The particular hypothesis is tested by the scientific experiments. The experiments include controls and the variables. The variable that are used as hypothesis is not controlled and the results are matched directly. The other variables are controlled as this includes the other alternative explanation of the particular result.

Thus, the correct answer is option (C).
