Which statement best describes bioethics?

• A. A branch of aesthetics
• B. A public health policy
• C. Application of ethics to medicine and all life sciences
• D. A field related to physics

Answer: (C)

Bioethics is the application of ethical principles to issues in medicine and all life sciences. It looks at how values, rights, and duties shape decisions in clinical care, research involving humans or animals, biotechnology, genetics, public health, and end-of-life issues. This broad focus—ethics applied across medical practice, research, and the life sciences—best describes bioethics.

Why this fits better than the others: it isn’t about beauty or art, which is what aesthetics covers. It isn’t limited to policy-making, even though bioethics influences policy; it also covers day-to-day clinical decisions, research ethics, and technology use. And it isn’t related to physics, which sits outside the life sciences domain.
