Answer:
The answer is Option C: The power to execute the law
Explanation:
The president has a duty to faithfully execute the laws that are passed by the House of Representatives and the Senate, regardless of how he personally feels about them and regardless of how his own administration views the legislation. It is Article Two of the United States Constitution that defines the executive branch and it describes the powers and responsibilities of the office of the president.
