The subject in an experiment that receives no real treatment would be receiving a placebo, which is a treatment that appears identical to the actual treatment being studied but contains no active substance. Placebos are used as a control in experiments to account for the placebo effect, which is when a subject's belief in a treatment's efficacy influences their response to it, regardless of whether the treatment actually has any active ingredients or not. Therefore, the correct answer is D.
