Answer

Brief Explanations:

In the study, some patients get a sugar - pill (placebo) and others get the actual medication. Blinding occurs when participants don't know if they are getting the real treatment or a placebo. There's no indication of stratification (grouping by characteristics), randomization (random assignment process details aren't given), or replication (repeating the experiment) in the description.

Answer:

B. blinding
