The answer is B thank u for your service bye

how nature would act without manipulation by the researchers

Explanation:

A control group is define as the group which does not receive any change or manipulation in an experiment. It is used as a benchmark or standard to measure and detect the changes occurring in the experimental variables.

As the experiment mimic those changes that occur in nature. The control group will represent the condition when the nature is without any manipulation or change.
