is it "A"

Yes, the answer is C. According to the American Psychological Association (APA), the ethics of informed consent require that research participants have the freedom to terminate their participation in a study. Participants should be given the ability to withdraw from the research at any time without facing any negative consequences or penalties. This ensures that participants have autonomy and control over their involvement in the study.
