Which of the following excerpts from the Constitution BEST demonstrates the constitutional principle of separation of powers?

A: "No Person shall be a Representative who shall not have attained to the Age of Twenty Five Years, and been seven years a citizen of the united states, and who shall not, when elected, be an inhabitant of the State in which he shall be chosen"
B: "The Vice president of the United States shall be President of the Senate, but shall have no vote, unless they be equally divided."
C: "Every Bill which shall have passed the House of Representatives and the Senate, shall, before it became law, be represented to the President of the United States."
D: " All legislative Powers herein granted shall be vested in a Congress of the United States."

D: " All legislative Powers herein granted shall be vested in a Congress of the United States."

This excerpt from the Constitution demonstrates the principle of separation of powers by clearly identifying that the power to make laws is vested solely in the legislative branch, which is the Congress. This shows the division of powers between the legislative, executive, and judicial branches, and how the legislative branch is separate and distinct from the other branches.
