The correct answer is A.
During the economic crisis of the 1930's, the government of Franklin D. Roosevelt applied a series of interventionist policies known as the "New Deal", launched to fight the effects of the Great Depression. This program was developed between 1933 and 1938 and focused in giving the federal government more power to assist the lower classes of society, the poor and unemployed in line with the politics of a welfare state, to intervene the markets in order to recover the economy to previous levels, and to reform the financial markets.
