Answer:
The correct answer is D. According to the Clayton Act, tying arrangements are illegal if they substantially lessen competition or create monopoly.
Explanation:
The Clayton Antitrust Act was a federal law passed in the United States in 1914, to remedy the deficiencies in the Sherman Antitrust antitrust law of 1890, the first federal law against business practices that would harm consumers (monopolies and collusive covenants against the competition).
Approved during the Woodrow Wilson administration, the legislation was introduced by Alabama Democratic Representative Henry De Lamar Clayton.
