Answer:
Breaching confidentiality
Explanation:
In any research, confidentiality is one of the most important subject matters for participants. Often, people only want to participate in research if they are sure that their privacy will be respected. If a researcher is using a small sample of people that belong to an easily distinguishable group of subjects, he should not use extensive quotes. Doing so might risk the privacy of the subjects, who could potentially be recognized, and this would risk the researcher breaching confidentiality.
