Final answer:
The U.S. Constitution can be amended with a two-thirds majority vote of both houses of Congress and a ratification vote by three-fourth of the states.
Step-by-step explanation:
The correct answer is: b) The Constitution can be amended with a two-thirds majority vote of both houses of Congress and a ratification vote by three-fourth of the states. This means that in order to make changes to the Constitution, it requires a significant amount of support from both Congress and the states. The process involves a two-thirds majority vote in both the House of Representatives and the Senate, followed by ratification by three-fourths of the states.
For example, if Congress wants to propose an amendment, it would require a two-thirds majority vote in both the House and the Senate. Once the amendment is proposed, it then needs to be ratified by three-fourths of the states. This ensures that any changes to the Constitution have widespread support and are not easily made.
