Which term best describes disease prevention, reducing risk of illness, promoting good health habits, and maintaining optimal functioning?

• A. Education
• B. Prevention
• C. Preventing illness
• D. Rehabilitation

Answer: (C)

The main idea here is actively avoiding disease through actions that reduce risk and help people stay as healthy as possible. Preventing illness best captures that ongoing, proactive effort to keep people from getting sick, by promoting healthy habits and reducing risk factors so functioning is maintained. Education plays an important role in prevention, but it’s a tool or method rather than the act of prevention itself. Rehabilitation focuses on recovery after illness, not preventing it. While prevention as a broader concept is related, the wording here aims for the action-oriented description, which is preventing illness.
