What is required for a constitutional amendment to be ratified?

• A. A majority vote in Congress
• B. Approval by three-fourths of state legislatures
• C. A public referendum
• D. Presidential approval

Answer: (B)

The requirement for a constitutional amendment to be ratified is that it must be approved by three-fourths of state legislatures. This means that after an amendment is proposed, it must be accepted by a substantial majority of state legislative bodies, ensuring broad support across the country. This process was established in Article V of the U.S. Constitution, which outlines both the proposal and ratification procedures for amendments.

Requiring the approval of three-fourths of the states (which equates to 38 out of 50 states) serves as a significant safeguard, ensuring that only amendments with widespread consensus can change the foundational legal framework of the nation. This high threshold reflects the framers' intent to protect the Constitution from frequent and potentially frivolous changes, maintaining its stability and integrity over time. In contrast, other choices such as a simple majority in Congress, a public referendum, or presidential approval do not fulfill the constitutional requirement for ratification and thus are not valid methods for this process.
