The 3Rs by Russell and Burch are known to be the "alternative methods" to improve the treatment of laboratory animals, at the same time to advance the quality of science that uses animals for studies.
The 3Rs are Replacement, Reduction, and Refinement. Replacement is defined as minimizing the pain and suffering of the animals used in research. Reduction is for reducing the number of animals being used, and using healthier animals. Replacement is using alternative to animals such as tissue cultures and computer models.

Answer:
The correct answer is: <em>B. A study of the types and prevalence of sexually transmitted infections (STIs) in small rural towns in a mid-western state.</em>
Explanation:
Sexually transmitted infections (STIs) is a topic that has had stigma, negative stereotypes and other negative connotations attached to it throughout history. If a study investigated the types and prevalence of STIs in small rural towns in a mid-western state, along with stigmatizing participants in the study, the results of this study could also potentially stigmatize residents of these towns by extrapolating claims such as "town <em>X </em>in this mid-western state has high prevalence of various types of STIs". These claims might make it seem like the presence of STIs is high in a given rural town (when this in fact might be untrue), especially considering the town is small in size. In this way, a study that investigates the types and prevalence of STIs in small rural towns in a mid-western state could produce harm to members of the sampled population who do not actually participate in the research study.
