Which laws does the FTC usually enforce?

The Federal Trade Commission (FTC) is primarily responsible for enforcing laws related to consumer protection and maintaining competition in the marketplace. The FTC Act is central to its operations, allowing the agency to take action against unfair or deceptive practices in commerce. Additionally, the Clayton Act, which addresses antitrust issues, prohibits certain business practices that could lead to anti-competitive behavior, such as mergers that may substantially lessen competition.

Thus, while the Sherman Act lays foundational principles regarding monopolistic practices and restraints of trade, it is the FTC Act and the Clayton Act that are directly enforced by the FTC. The combination of these two laws enables the FTC to effectively regulate market practices and protect consumer interests. This is why the correct answer involves both the Clayton Act and the FTC Act, illustrating the scope of the FTC's enforcement authority.
