What is the primary function of the Federal Trade Commission (FTC) in the United States?

The primary function of the Federal Trade Commission (FTC) in the United States is to collect complaints about companies and enforce consumer protection laws. This involves safeguarding consumers from deceptive and unfair business practices, ensuring that they can make informed choices in the marketplace. The FTC also investigates complaints, conducts research, and takes legal action against companies that engage in fraud or violate consumer protection laws.

The role of the FTC is pivotal in promoting consumer welfare and maintaining competition among businesses, which ultimately leads to a healthier economy. By implementing regulations and enforcing compliance, the FTC strives to protect consumers' rights and interests, which is a fundamental aspect of its mandate.

In this context, other options represent functions carried out by different entities or agencies that do not accurately reflect the FTC’s core responsibilities. For example, regulating financial transactions is primarily under the purview of financial regulatory agencies, international trade agreements fall within the domain of trade departments, and environmental regulations are typically enforced by environmental protection agencies.
