Final answer:
Procter & Gamble's Code of Ethics covers fair competition, protection of confidential information, and environmental sustainability but does not include unethical practices such as price manipulation which comprises predatory pricing.
Step-by-step explanation:
The options listed pertain to aspects generally encompassed within a company's code of ethics. Procter & Gamble's Code of Ethics includes policies on fair competition, which refers to following laws that prohibit anti-competitive behaviors; confidential information, which may include trade secrets or company practices that are to be kept secure; and environmental sustainability, showing a commitment to eco-friendly business practices. However, price manipulation, which can involve unethical actions like predatory pricing to dissuade competition or cosmetic pricing to deceive consumers, would not be included in their code of ethics. Predatory pricing specifically is when an existing firm uses sharp but temporary price cuts to discourage new competition, which is unethical and often illegal. In addition, trademarks, which are identifying symbols or names for goods that can only be used by the firm that registered them, protect a company's brand and are a part of fair competition practices.
