What is the principal mission of the FTC?

The principal mission of the Federal Trade Commission (FTC) is to enforce civil U.S. antitrust law and protect consumers. This involves promoting fair competition in the marketplace and preventing deceptive or unfair business practices that can harm consumers. The FTC plays a critical role in ensuring that companies do not engage in anti-competitive behaviors that could stifle innovation or limit choices for consumers. It also addresses issues related to consumer rights and privacy, ensuring that businesses are held accountable for their practices.

While promoting technological advancements, regulating IoT device manufacturers, and setting international cybersecurity standards are important areas of focus for various governmental entities or agencies, they do not directly align with the core mission of the FTC. The FTC's foundational purpose is centered around antitrust enforcement and protecting consumer interests, making it the correct response for this question.
