Answer:
The correct answer is D. In American foreign policy, the president is the chief diplomat, the commander in chief and the head of the federal bureaucracy.
Step-by-step explanation:
Together with leadership of the armed forces, the president is also at the forefront of foreign policy. Through the Department of State and the Department of Defense, the president is responsible for the protection of Americans abroad and foreign citizens in the United States. The president decides whether to recognize new nations and new governments and negotiates treaties with other nations, which become effective in the United States when they are approved by two-thirds of the Senate. The president can also negotiate "executive agreements" with foreign powers that are not subject to Senate confirmation.
