Which of the following is one of the five sciences of public health?

• A. Epidemiology, Biostatistics, Social and Behavioral Sciences, Environmental Health, Health and Policy Management
• B. Epidemiology, Microbiology, Immunology, Pathology, Pharmacology
• C. Public Health, Medicine, Nursing, Dentistry, Pharmacy
• D. Genetics, Ecology, Microbiology, Immunology, Virology

Answer: (A)

The question tests which disciplines are recognized as the five core sciences of public health. Public health relies on these lenses to study population health, measure outcomes, and design effective interventions. The five core sciences are epidemiology (how disease occurs and spreads in groups), biostatistics (the methods for analyzing health data and drawing valid conclusions), social and behavioral sciences (how behavior and social factors influence health), environmental health (how the environment affects health and safety), and health policy and management (how health systems are organized, financed, and led to improve health outcomes). This combination provides both the tools to measure health and the contexts in which health is produced and managed, making it the best fit.

Other options mix in biomedical sciences like microbiology, immunology, pathology, and pharmacology, which are essential to medicine and laboratory research but not the five core public health sciences as a framework. Another choice lists professional fields or non-discipline groupings rather than the specific public health science domains. A final set includes broader life sciences rather than the established public health disciplines.
