What is required for Congress to override a presidential veto?

• A. A simple majority vote in both houses
• B. A three-fourths vote in both houses
• C. A two-thirds vote in both houses
• D. A unanimous decision

Answer: (C)

To override a presidential veto, Congress must achieve a two-thirds vote in both the House of Representatives and the Senate. This threshold ensures that there is significant bipartisan support for the legislation and reflects the framers' intent to balance power between the legislative and executive branches. The process establishes a check on presidential power while allowing Congress to assert its legislative will under certain conditions, demonstrating the system of checks and balances that is foundational to the U.S. government.

The alternative options do not align with the constitutional requirement for overriding a veto. A simple majority is insufficient as it does not provide the necessary consensus among lawmakers to counteract a presidential decision. A three-fourths vote and a unanimous decision are both beyond what is specified in the Constitution, making them impractical and unlikely for typical legislative processes.
