Answer:
<h2>C) large sample size, with a large group of participants and many trials.</h2>

So, to prevent any type of subjectivity, a certified committee has to test this drug to demonstrate what the experimenter is claiming. The best ways to demonstrate the effectiveness of the drug is by experimenting with a large size, a large groups of participants, and with many trials. Doing this, they will experiment enough to see if the drug works or doesn't, the more trials they do using a large size, the most effective or not can the drug be.
Testing with this conditions, they will observe the drug in different kind of circumstances.

Therefore, the right answer is C.
