Answer:
The set of pepper plants in the fourth box are the control group
Explanation:
The aim of the experiment is to determine the plant fertilizer that will give the most pepper yield
The number of types of fertilizers used under the study = 3 brands
The number of boxes set up for the experiment = 4 boxes
The number of pepper plants planted in each box = 3 sets
The fertilizers applied to each box = One different type for each of the first three box
The type of fertilizer applied to the fourth box = No fertilizer

Therefore;
The set of pepper plants in the fourth box are the control group.
