Which law addresses unfair or deceptive acts or practices in commerce?

The Federal Trade Commission Act (FTC Act) is the correct choice as it specifically addresses unfair or deceptive acts or practices in commerce. Enacted in 1914, this act established the Federal Trade Commission (FTC) to enforce laws regarding unfair competition and unfair or deceptive business practices. The FTC has the authority to investigate companies and individuals who engage in such practices, ensuring that consumers are protected from misleading advertising and other forms of deception in the marketplace.

This act is foundational in consumer protection law in the United States, as it allows for the regulation of a wide range of business practices that might harm consumers or competition, making it a crucial element in maintaining fair commercial conduct. Other laws like the Sherman Act and the Clayton Act primarily focus on antitrust issues and the regulation of monopolies, while the Robinson-Patman Act deals specifically with price discrimination in certain sales contexts. Thus, the FTC Act stands out for its explicit aim to curb deceptive practices directly affecting consumer and market integrity.
