In US V US

In U.S. v. U.S. Steel Corporation , the Supreme Court ruled that

B) despite the fact that U.S. Steel controlled 50 percent of output in the steel industry, the company had not achieved monopoly power.
C) large corporations, by definition, violate the Sherman Act.
D) the Sherman Act did not apply to U.S. Steel because steel manufacturing was an activity "clothed with a public interest."
