Explanation:

In a clinical trial with an active control, the experimental treatment is compared to a medicine that has a known effect on the disease under study. A placebo is used in placebo - controlled trials, not active - control trials. Comparing to “nothing” is not typical in an active - control trial setup, and comparing to another experimental treatment is not what an active control is about (active control uses a known - effective treatment). So option C is correct.

Answer:

C. A medicine with known effect in the disease being studied
