The correct answer is D) the judicial power to decide whether a law is Constitutional.
What was firmly established in the Supreme Court case of Marbury v. Madison was "the judicial power to decide whether a law is Constitutional."
In this case of February 24, 1803, the Supreme Court of the United States established the process of judicial review, that is the power of the US courts to stop laws or government actions and decision that seem to violate the Constitution. Through this process, the Supreme Court can revise or evaluate decisions made by the legislative branch and the executive branch.
