Final answer:
Ethics does indeed entail making rational choices among a variety of morally justifiable options, with some being more ethical than others, aligning with the principles of normative and applied ethics.
Step-by-step explanation:
Ethics involves rational decision-making among an array of choices, and it is true that these choices may all be morally justifiable, but some may be more so than others. This is a core aspect of normative ethics, which concerns itself with setting standards or norms for right and wrong behavior.
Applied ethics goes further by examining specific controversial issues, such as environmental ethics, biomedical ethics, or business ethics. In the context of ethics, making rational decisions involves using reasoning, understanding moral principles, and considering the consequences, duties, or virtues that may apply to any given situation.
