An experiment must have a control to show what would happen if no factors were changed.
Variables
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
A control group is must for every new experiment or uncommon experiment. Because when an experiment is being done anything unexpected could happen and to control the hazard a control group should be ready everytime. Otherwise it can be very dangerous for the experiment holders. to help you conclude that no uncontrolled factors significantly influenced your results
A controlled experiment is one in which a control group is closely monitored. In this way, the experiment can be much more accurate as more factors are accounted for.

Because if you have any unknown factors you wont know how the experiment will react in any given situation.
control group and placebo group variable and controlled
The answer is /
