supporters of the sherman antitrust act of 1890 believed that regulation of
business protected consumers.
trade helped large companies.
taxes assisted consumers.
services helped large companies.

Explanation:

The Sherman Antitrust Act of 1890 was aimed at regulating business to prevent monopolies and unfair business practices. Supporters believed that regulating business (like breaking up monopolies) would protect consumers from high prices and limited choices. The other options are incorrect: trade regulation under the act was to prevent large companies from monopolizing, not help them; taxes weren't the focus of this act; and services helping large companies goes against the act's purpose.

Answer:

A. business protected consumers
