if an institutional review board is involved in a request for information, the information is likely sought by a

a. health care facility
b. researcher
c. court
d. substance abuse center

I think it would be a court

The answer is b. researcher.

To arrive at this answer, let's understand the role of an Institutional Review Board (IRB). An IRB is a committee that has the responsibility to review, approve, and oversee research involving human participants. It ensures that the rights, welfare, and safety of the participants are protected.

When an IRB is involved in a request for information, it typically means that a researcher has submitted a proposal to conduct a study involving human subjects. The researcher needs to obtain approval from the IRB before they can collect data or interact with participants.

Therefore, the information being sought is likely by a researcher who is subject to the review and oversight of an IRB. This ensures that the research is conducted ethically and the rights of the participants are protected.
