The reason that the President is called the Commander-in-Chief in the Constitution is because the Framers wanted (Points : 1)

to provide the President with authority over the secretary of defense.
to establish the principle of civilian control of the armed forces.
to establish a basis for presidential prerogative.
to give the President some power against impeachment.

to establish the principle of civilian control of the armed forces

I agree.

an agency is in the service of its clientele and their interests come before the public’s interest

If it's a government agency, the theoretical answer is NO. The public interest comes first.

To determine the reason the President is called the Commander-in-Chief in the Constitution, we will need to refer to the document and understand the intentions of the Framers.

The term "Commander-in-Chief" refers to the role of being the highest-ranking officer of a military force. In the context of the President of the United States, this title carries significant importance and responsibilities. The Constitution bestows upon the President the title of Commander-in-Chief in Article II, Section 2, Clause 1.

The Framers of the Constitution had several reasons for designating the President as the Commander-in-Chief:

1. To establish the principle of civilian control of the armed forces: The Framers wanted to ensure that the military would always be under civilian authority and control. By making the President the Commander-in-Chief, they established a clear separation between military and civilian leadership.

2. To provide the President with authority over the secretary of defense: The President's role as Commander-in-Chief gives them ultimate authority over the armed forces, including the power to direct military operations and make strategic decisions. This includes the authority to appoint and oversee the Secretary of Defense, who serves as the civilian head of the Department of Defense.

3. To establish a basis for presidential prerogative: The title of Commander-in-Chief gives the President certain inherent powers in times of national crisis or warfare. This authority allows the President to respond swiftly and effectively to protect the nation's interests and security.

4. To provide the President with some power against impeachment: Although not explicitly stated in the Constitution, it has been argued that the inclusion of the Commander-in-Chief clause provides the President with a measure of power and authority that acts as a check against potential impeachment. The argument suggests that removing a President who serves as Commander-in-Chief could disrupt national security and military operations.

In summary, the Framers included the title "Commander-in-Chief" in the Constitution for multiple reasons, including establishing civilian control over the military, granting the President authority over the Secretary of Defense, allowing for presidential prerogative in times of crisis, and potentially providing the President with some power against impeachment.
