A) Tomato plants grown in soil with no fertilizer

Explanation:

The control group is the group that you do not change anything. This is used as a basis or a baseline to determine whether changes you make in the experimental groups actually made a difference. An experiment is incomplete when you do not have this because it does not show any evidence that the change you made is what ellicits an effect.
