Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.

Choice C is incorrect as deciding who will be involved in a conference is not the primary step in combating myths and misconceptions.
