Public health focuses on promoting and protecting the health of populations — especially through health promotion and disease prevention.

1. Relevant knowledge points and concepts
- Public health is the science and practice of preventing disease, prolonging life, and promoting health through organized community efforts (Winslow’s classic definition).
- Key activities include health promotion, disease surveillance, epidemiology, sanitation, vaccination programs, policy, and health education.
- Distinction: clinical medicine primarily treats individuals; public health targets populations and prevention.

2. Step-by-step reasoning
- Step 1: Identify the primary aim of public health: population-level prevention and health improvement.
- Step 2: Compare each answer option to that aim.
- Step 3: Select the option that best matches population-level prevention and promotion.

3. Calculations or intermediate steps
- No numerical calculations are required for this conceptual question.

4. Why the correct answer is correct
- “Health promotion” aligns directly with promoting healthy behaviors, environments, and policies for populations (e.g., anti-smoking campaigns, school nutrition programs, vaccination promotion). These activities are central to public health’s mission to prevent illness before it occurs and improve community well-being.

5. Why the other options are incorrect
- a. Treatment of diseases: This is primarily the role of clinical medicine and healthcare providers treating individuals (diagnosis, medical/surgical care). While public health can support care access, treatment is not its primary focus.
- c. Personal health: Personal health refers to an individual’s health behaviors and care; public health addresses population-level determinants and interventions rather than only individual personal health management.

6. Conclusion
- Based on the definition and goals of public health, the best answer is b. Health promotion. This matches the provided correct answer: Health promotion.
