Which example demonstrates the principle of beneficence in research studies?

The principle of beneficence in research focuses on maximizing benefits and minimizing any potential harm to participants. It requires researchers to take measures that ensure the welfare and well-being of individuals involved in a study. Choosing an option that indicates reasonable risks in relation to anticipated benefits clearly illustrates this principle, as it emphasizes the importance of carefully weighing potential harms against the expected positive outcomes for participants and society at large.

In this context, ensuring reasonable risks relative to anticipated benefits aligns with the ethical obligation researchers have to protect participants from undue harm while striving to achieve meaningful results. This demonstrates a thoughtful consideration of participant welfare and the overall goals of the research.

Other options do not directly illustrate the principle of beneficence. Obtaining informed consent is vital for respecting autonomy, while conducting research in secrecy may undermine trust and ethical transparency. Recruiting vulnerable populations, although necessary under certain ethical guidelines, does not inherently reflect beneficence unless accompanied by careful consideration of risks and benefits.
