Answer: (B)

Public health is defined as the science of protecting and improving the health of communities through education, promotion of healthy lifestyles, and research on disease prevention. This definition encompasses the core functions of public health, which include assessing health needs of populations, creating programs to foster healthier behaviors, and conducting research to identify effective strategies for preventing diseases. The focus on community health rather than individual patient care underscores the broader mission of public health, which aims to improve the well-being of entire populations rather than just treating individuals after they become ill. This includes initiatives such as vaccination programs, health education campaigns, and policies that facilitate access to clean water and nutritious food. By addressing the social determinants of health and implementing preventative strategies, public health professionals aim to reduce health disparities and improve overall community health outcomes. The emphasis on education and promoting healthy lifestyles shows the proactive approach of public health, contrasting with reactive healthcare models that focus primarily on treatment after disease onset.
