Your psychology professor is conducting research and desperately needs more research participants because the existing subjects keep running from the building screaming! she tells the class that everyone must be a subject to get a grade in the class and that there are no exceptions. in terms of ethical treatment of research subjects, her policy would: a. violate the informed consent concept of competence b. be acceptable as long as her procedures were presented to the institutional review board c. be acceptable if she carefully explained the experiment to each participant and did allow participants to quit if they were uncomfortable during the procedure d. violate the informed consent concept of volunteerism
