Final answer:
The domestic policies of President Harding, Coolidge, and Hoover were characterized by less business regulation and increased tariffs, focusing on pro-business policies and reduced government intervention in the economy. The correct option is (B).
Step-by-step explanation:
The domestic policies of President Harding, Coolidge, and Hoover would BEST be characterized by less business regulation and increased tariffs. These Republican presidents of the 1920s placed a high priority on pro-business policies.
They aimed to create a business-friendly environment with lower federal spending and reduced government intervention in the economy.
President Harding, for instance, put measures into place that decreased the debt and applied tariffs to protect U.S. agriculture and business.
Likewise, President Coolidge continued these policies, focusing on reducing taxes and maintaining economic prosperity.
President Hoover's early presidency reflected a similar sentiment, as he advocated for rugged individualism and minimal government intervention, although later he also had to initiate some federal interventions to combat the Great Depression.
Increased tariffs such as those from the Emergency Tariff of 1921 further reinforced this approach by protecting domestic industries.
