Answer:
(C) Not approve this project because the prisoners are merely a population of convenience for the student.
Step-by-step explanation:
This is most likely what would happen with the IRB. An IRB is an institutional review board. This is a type of committee that reviews the ethics of the methods used in a research project. In this case, the IRB is most likely not going to be approved because the reason why the student is using a population of prisoners is merely out of convenience, and not because it is actually relevant to the study.
