Step-by-step explanation:
Ethics is the field of philosophy that investigates morality and engages in "systematizing, defending, and recommending concepts of right and wrong behavior". It is divided into three main areas: metaethics, normative ethics, and applied ethics - each of which is distinguished by a different level of inquiry and analysis.
