Answer:
Option D. In order to improve the economy, President Reagan believed the government should become smaller and more efficient.
Step-by-step explanation:
When President Reagan took power over the Presidency of the United States, in 1981, the country was submerged in a stagflation. To combat it, the ex-President aggressively cut a series of taxes, like income and corporate, and started to deregulate the market in order to combat the high inflation rates. He also believed in a reduced government role and government spending, which ultimately he failed to conduct successfully, as he had to increase the defense spending for the Cold War.
