What practice does the Clayton Act outlaw?

The correct answer is that the Clayton Act specifically addresses bundling sales conditions, among other anti-competitive practices. Enacted in 1914, the Clayton Act serves to enhance previous antitrust laws, particularly by regulating specific practices that could lead to anticompetitive behavior.

One notable aspect of the Clayton Act is its prohibition against tying arrangements, which involves requiring customers to purchase a secondary product when they buy a primary product. This can stifle competition by forcing consumers into purchases they might not make otherwise, thereby reducing their choices in the market.

While the other options relate to various aspects of antitrust and consumer protection laws, they are addressed primarily under different regulations. For example, price fixing is a violation of the Sherman Act, misleading advertising practices are typically regulated under the Federal Trade Commission regulations, and market monopolization also falls under the Sherman Act. The Clayton Act's focus on bundling sales conditions distinguishes it in the context of antitrust regulations, making it a key law in promoting fair competition in the marketplace.
