The correct answer for this is D: the president cannot make serious decisions without input from Congress. This can be told from the text itself, where the President says: "...because there are serious, very serious, choices of policy to be made, and made immediately, which it was neither right nor constitutionally permissible that I should assume the responsibility of making." This speech was historically given by President Woodrow Wilson in 1917, before Congress, as he persuaded this institution to declare war on Germany as response to Germany´s submarine warfare, which allowed German submaries to attack any vessels that were found in the waters of the British Isles. After this, the United States, in a unified declaration of war, which was voted almost unanimously by members of Congress, entered the First World War.
