Which organization is responsible for the enforcement of consumer protection laws in the U.S.?

The Federal Trade Commission (FTC) is the organization responsible for the enforcement of consumer protection laws in the United States. Established in 1914, the FTC's primary mission is to protect consumers by preventing anti-competitive, deceptive, and unfair business practices. This includes overseeing a wide range of consumer issues, such as privacy, fraud, and advertising practices, ensuring that businesses act fairly towards consumers and that consumers have access to the information they need to make informed decisions.

The FTC plays a crucial role in regulating various sectors of the economy by investigating consumer complaints, enforcing federal statutes related to consumer protection, and educating consumers about their rights. Its ability to take legal action against companies that engage in misleading advertising or practices makes it a key player in protecting consumers' interests.

While the other organizations listed have important functions in their respective areas—such as labor relations, securities regulation, and environmental protection—they do not focus primarily on consumer protection laws. This specialization makes the FTC the correct organization in the context of this question.
