A simple reversal design (ABA) involves the baseline condition, followed by the experimental condition, and then back to the baseline condition again. Therefore, the design concludes with subjects under the baseline condition. The design does not involve more than two different treatments (C) or two groups (D) because it is a single-subject design where the same participant serves as both the experimental and control group.
