The correct answer is D.
In 1933, upon learning that the banks of Illinois and New York had stopped working, Herbert Hoover said his sadly famous phrase: "We are at the end of our string. There is nothing more we can do."
Hoover feared that the crisis would lead to the development of right-wing totalitarian policies, such as Nazism, which had developed out of a similar crisis in Germany. The phrase is directly related to this fear.
The phrase was pronounced on March 3, 1933, a day before leaving his position in the hands of Franklin D. Roosevelt, who through his New Deal policies could get the United States out of the crisis.
