Final answer:
The correct order of succession for the roles listed is: Secretary of the Treasury, Secretary of Defense, and then Attorney General. This is based on the chronological order of the creation of their cabinet positions as outlined by the 25th Amendment and the Presidential Succession Act of 1947.
Step-by-step explanation:
The line of succession to the presidency is a system detailed in the 25th Amendment of the U.S. Constitution and the Presidential Succession Act of 1947, which outlines the order in which government officials will assume the role of President of the United States in the event that the President and Vice President are unable to fulfill their duties. When considering the specific order for the officials mentioned: the Secretary of the Treasury, the Secretary of Defense, and the Attorney General, the correct order of succession would be:
- Secretary of the Treasury
- Secretary of Defense
- Attorney General
This order is determined by the chronological creation of their respective positions within the Cabinet. If the President and Vice President can no longer serve, the Speaker of the House would take office, followed by the President pro tempore of the Senate, and then Cabinet members in the order their positions were created, starting with the Secretary of State.
