A within-subjects experimental design involves each participant being exposed to all of the treatment conditions, allowing for a comparison of changes within the same individuals. Therefore, option C is the correct choice. Option A is describing a placebo-controlled experimental design.

Option D describes a between-subjects experimental design, where groups are compared rather than individuals across conditions.
