Multiple Choice

(Scenario II) . Suppose the researchers wanted to examine whether e-cigs were indeed less harmful than cigarettes to adolescents' health, and proposed to recruit 1000 10^th graders who would be randomly assigned to use e-cigs or cigarettes for 6 months after which they would be examined by a medical doctor. Upon receiving this proposal, the IRB at the researchers' university quickly denied their application. Which of the following reasons for denying the application is most likely?

• A) It is not just to recruit only 10^th graders.
• B) The researchers lack of requiring both parental consent and participant assent.
• C) The cost-benefit analysis suggested the study was too risky and reward too small.
• D) Psychological harm to the participants was too great.
