Answer:
Since this research involves individual subjects who would be considered prisoners and examines the possible causes, effects, and processes of incarceration, the IRB should ensure that the additional requirements for prisoner research are met.
Step-by-step explanation:
The Institutional Review Board or IRB, is an institution with the sole purpose of ensuring that the rights and welfare of research subjects are met and protected. Whenever there are human participants in a research, the IRB has to intervine and review the guidelines of the research and the research information per se in order to protect those who will be studied in it. Which is why the option provided as the answer best fits the IRB's role and purpose.
