Final Answer :
D
Explanation :
Dr. Logan must control for all three potential effects in his study. Spontaneous improvement refers to the natural recovery that may occur without any intervention; placebo effect refers to the changes that may occur due to an individual's belief in the treatment's effectiveness; and preexisting differences between patients in the control and treatment groups may affect the outcome of the study, so they need to be accounted for in the study design.
