• A. It established the right to vote
• B. It established the principle of judicial review
• C. It defined the powers of the Executive Branch
• D. It regulated interstate commerce

Answer: (B)

The significance of Marbury v. Madison lies in its establishment of the principle of judicial review, which grants the Supreme Court the authority to invalidate laws and executive actions that it finds to be in conflict with the Constitution. This landmark case in 1803 set a precedent that empowered the judiciary, allowing it to ensure that no law or government action can supersede the Constitution's authority. By affirming this function, the Supreme Court became a critical arbiter in the balance of power among the branches of government, thereby solidifying the role of the judiciary in protecting constitutional principles. This principle of judicial review remains a cornerstone of American constitutional law and is fundamental in interpreting the limits and application of legislative acts and executive orders.
