Final answer:
Deceptive advertising and its moral implications are discussed in the context of different branches of ethics: normative ethics and metaethics.
Step-by-step explanation:
The first statement matches with (b) Normative Ethics. Normative ethics focuses on moral behavior and determining what we should do. It establishes criteria and principles for identifying norms and standards of correct behavior. In this case, many people in the US believe that deceptive advertising is morally wrong because it undermines personal autonomy.
The second statement matches with (a) Metaethics. Metaethics focuses on moral reasoning and foundational questions. It explores the assumptions related to moral beliefs and practice, including the origin of moral values and the existence of objective moral facts. In this case, it questions whether deceptive advertising is morally wrong.
The third statement matches with (b) Metaethics. It states that there are no objective moral truths, and personal opinions determine whether or not deceptive advertising is morally wrong. This reflects the focus of metaethics on exploring the basis for moral practices and value judgments.
