Final answer:
The first three Articles of the Constitution establish the Legislative, Executive, and Judicial Branches, thereby demonstrating the principle of separation of powers, which ensures that no single branch becomes too powerful. The correct answer is option D.
Step-by-step explanation:
The first three Articles of the Constitution establish the Legislative Branch, the Executive Branch, and the Judicial Branch. This organization demonstrates the Constitutional principle of separation of powers. This principle is essential to prevent any one branch from becoming too powerful and to ensure a system of checks and balances. Each branch has distinct and separate powers, but also requires the approval or cooperation of the other branches to fulfill its duties, as seen in the Constitution's outlined checks that each branch has over the others.
For example, Congress (the legislative branch) has the power to draft legislation, but the President (executive branch) must sign the proposed legislation before it becomes law. Also, the judicial branch, through judicial review, can interpret the laws and determine their constitutionality. This framework creates a balance that the Founding Fathers believed was necessary to protect individual freedoms and maintain a fair government system.
