Final answer:
The answer is d. small group. Ethics is addressed at the personal, industry, and global levels, but 'small group' is not recognized as a distinct level of ethical analysis in the same sense as the others.
Step-by-step explanation:
Which of the following is not a level at which ethics may be addressed? The correct answer is d. small group. The common levels at which ethics are addressed typically include personal, industry, and global dimensions. Personal ethics involve the principles that guide the behavior of individuals in their private lives. Industry ethics or professional ethics relate to behavioral standards within specific occupations or sectors. Global ethics consider moral issues with a worldwide impact, such as climate change or human rights.
While small groups within a society can have shared norms and beliefs that might influence individual behaviors, they are generally not recognized as a distinct level of ethical analysis like the other options provided. Ethics can certainly emerge within small groups, but there is not an established field of 'small group ethics' as there is with personal, industry, and global ethics.
Other concepts of ethical discussions often touch upon applied ethics, which addresses practical moral concerns in various domains, including bioethics, environmental ethics, and business ethics, along with discussions on emerging technologies and their impact on society.
