The correct answer is B. Restore competition in business
Step-by-step explanation:
The Sherman Antitrust Act approved in 1890 aimed at stopping unfair competition such as monopolization and in this way allow all businesses to have an opportunity to compete in the U.S. market. Indeed, the act made illegal the use of alliances and unfair strategies to control the market. This was effective to restore competition and protect consumers from the abuses and actions of some businesses. Thus, the act was an effort to "Restore competition in business".
