How does Subpart A define a human subject?

The definition of a human subject in Subpart A is focused specifically on individuals who are alive and involved in research activities. Thus, a human subject is defined as a living individual about whom research is conducted. This definition emphasizes the importance of informed consent and ethical considerations when research involves individuals, as their rights and welfare must be prioritized.

By delineating a human subject as a living person, it establishes clear ethical guidelines for conducting research, ensuring that individuals who are part of studies are safeguarded. The other options do not align with this definition; for example, deceased individuals do not fall under this classification as they cannot provide consent or participate in research activities in the present context. Similarly, individuals providing consent for others or simply participating in non-experimental studies do not meet the specific criteria established for a human subject in the context of research ethics.
