Answer:
A). A study of the types and prevalence of sexually transmitted infections (STIs) in small rural towns in a midwestern state.
Step-by-step explanation:
The first option most adequately exemplifies the research type that will lead to harm among the group through condemnation of the group members. 'A research of the kinds of STIs(sexually transmitted infections) and their frequency among the people in rural towns.' Since this is a sensitive topic for the rural people and they would not accept it if they have any such disease instead they would blame the other people of the community leading to mistreatment of one another among the group members themselves. Thus, option A is the correct answer.
