Final answer:
The president's roles have expanded beyond what the Constitution originally intended, but they are subject to checks by Congress and the judiciary, ensuring a balance of power. These roles are based on specific constitutional grants, implied powers, and the evolution of laws over time. Therefore correct option is C
Step-by-step explanation:
The president's constitutional roles, such as chief executive and commander in chief, have expanded in practice to be more powerful than the writers of the Constitution intended. While the Constitution vests the President with specific powers, including being the commander-in-chief of the armed forces, the authority to appoint officials, and the role in foreign policy as America's chief diplomat, these powers are not absolute. Over time, presidents have claimed inherent powers not explicitly stated in the Constitution but implied by its language and have utilized tools like executive orders to extend their influence. However, these roles and actions are subject to checks by Congress and the judiciary, as envisioned by the founders to prevent any single branch from gaining too much power.
Presidential power, especially during times of war or international crisis, has indeed grown, sometimes with the assistance of Congress. Nonetheless, this expansion is not rooted in tradition only but is also based on the Constitution's language and subsequent laws like the War Powers Resolution. The balance of power and the separation of powers between the branches remain a central feature of the U.S. government, ensuring that the powers of the president are not without limits and are checked by the other branches.
