Final answer:
The Lanham Act empowers companies to sue competitors over deceptive advertising claims, focusing on false or misleading statements that deceive consumers. The correct option is c.
Step-by-step explanation:
The act that gives companies the right to sue a competitor for making deceptive advertising claims is the Lanham Act. While acts like the Sherman Antitrust Act and the Clayton Antitrust Act were fundamental in dealing with unfair competition, price fixing, and other anti-competitive practices, the Lanham Act specifically provides a means for companies to address false advertising.
Specifically, it allows a company to sue another if the latter makes false or misleading statements in their advertising that could deceive consumers and affect the plaintiff's business.
Hence, Option c is correct.
