What does the study of ethics primarily concern itself with?

The study of ethics primarily concerns itself with moral duty, emphasizing the principles and values that guide individual behavior and decision-making regarding what is right and wrong. It involves analyzing concepts such as justice, virtue, and the good life, as well as how individuals ought to act in various situations based on moral reasoning. This focus on moral duty is foundational to ethical theories and frameworks that seek to provide guidance on conduct in personal, professional, and societal contexts.

The other options, while related to human behavior and societal structures, do not encapsulate the core focus of ethics. Legal obligations pertain to the laws and regulations that govern society, economic decisions revolve around financial matters and resource allocation, and social interactions are about the relationships and communications between individuals or groups. While these areas can intersect with ethical considerations, they do not constitute the primary concern of ethics itself.
