Why Should a Qualitative Research Proposal Intended for Institutional Board

Why should a qualitative research proposal intended for institutional board review address methods, since methods can be flexible in qualitative research?

A) The committee must be aware of anything that will be done to the participants, including interviewing.
B) The committee must adjudge potential harm that emanates from discussion of disturbing topics.
C) The committee must be apprised of planned methods at the beginning of the study; researchers must ask for permission if they decide add anything to the methods, while the study is in progress
D) The forms for institutional review include this section, but it isn't really addressed in qualitative research, since there is no intervention, per se.
E) The committee must determine the relative risk of accidental disclosure of potentially embarrassing information.
