Which of the following describes both a breach of confidentiality and a violation of subjects' privacy?

The scenario describing a breach of confidentiality and a violation of subjects' privacy is when a faculty member makes identifiable data about sexual behavior available to graduate students. This situation involves sharing specific and sensitive information that can be traced back to individual subjects, thereby compromising their confidentiality.

When identifiable data is disclosed, it means that individuals in the study can potentially be recognized and their private behaviors exposed. This is particularly concerning when the data pertains to sensitive topics, such as sexual behavior, which are generally considered private. Such disclosure not only violates the ethical principle of confidentiality—which is designed to protect the identity and information of research participants—but also infringes on their privacy rights by making personal information accessible to others who are not authorized to view it.

In contrast, the other options do not pose the same level of risk to confidentiality and privacy. Group data analysis results are typically anonymized and do not identify individual participants, sharing data only with fellow researchers usually implies a controlled environment respecting confidentiality, and discussing client information in a public forum presents ethical issues but does not necessarily indicate sensitive identifiable data unless specified.
