Answer 1

Answer:

B. The rose bushes without the deer repellent

Explanation:

In an experiment, the control group is often the group that is not exposed to the independent variable.

The control group is usually used for comparison between it and the experimental groups.

In this experiment, the rose bushes without the deer repellent are the control group.

As the control group, these rose bushes will be compared to the ones that have deer repellent.

The correct answer is B. The rose bushes without the deer repellent
