Answer:
D. The new deal proved that the united states had to go back to an unregulated economy.
Step-by-step explanation:
The New Deal was a series of measures and projects enacted during Franklin D. Roosevelt's administration that aimed at helping the U.S. economy to recover during the Great Depression and to provide relief to struggling Americans.
Under this program, the government actively participated in the nation's affairs and increased government spending to create several federal agencies to put people back to work (like the Civilian Conservation Corps and the Works Progress Administration), which helped to reduce the unemployment rates, to regulate the banking industry, to improve the nation's infrastructure, and to create laws that would benefit the most in need like the Social Security Act.
So, the New Deal achieved all options A, B and C. But option D is not a true statement, because under this program, the government indeed regulated the economy and those measures had a positive effect on the U.S. economy and American lives.
