According to the four branches of philosophy, what is ethics the study of?

Philosophy is traditionally divided into several main branches. Metaphysics is the study of existence and very basic ideas (Option B). Epistemology is the study of knowledge itself, how we acquire it, and its limits (Option C). Logic is the study of the rules of valid reasoning and argumentation (Option D). Ethics (also known as moral philosophy) is specifically defined as the study of right and wrong, good and evil, and the moral principles that govern a person's behavior or the conducting of an activity. In the context of professional practice, studying ethics involves understanding how to systematically evaluate complex situations, balance competing duties (e.g., duty to employer vs. duty to the public), and determine the most morally defensible course of action. It provides the intellectual framework necessary for professionals to navigate the grey areas of technology, business, and law while maintaining their integrity.
