Ответ:
The correct answer will be option-having a constant in your experiment
Explanation:
A scientific experiment is designed in a way that it tests the predicted hypothesis related to the natural event.
The hypothesis can be tested only after the collection of the result is done in a proper way as the errors done while collecting the results can lead to the errors in results and hence the hypothesis cannot be tested.
In the given question, the collection of the results is not influenced by having a constant variable in the experiment which is the variable which remains the same and does bot change throughout the experiment.
Thus, the selected option is the correct answer.
