Question

Quizplus · Accepted Answer

A placebo is a treatment or intervention that appears to be real, but has no active ingredients or therapeutic benefit. It is often used in clinical trials as a control to compare the effects of a new drug against a placebo. In this context, option A refers to a diagnostic test, not a placebo; option C refers to the effects of a real treatment, not a placebo; and option D refers to a medication with active ingredients, not a placebo. Option B, however, describes a pill with inactive ingredients that is intended to mimic the appearance and taste of a real drug, but does not contain any therapeutic ingredients.
