Final answer:
The Congress is needed in the process to propose the amendment while the states get final approval.
Step-by-step explanation:
The correct option is C. In all cases, the Congress is needed in the process to propose the amendment while the states get final approval.
Amending the Constitution is a two-step process that typically requires action from both Congress and state legislatures. To propose an amendment, two-thirds of both chambers of Congress must agree to the proposal, or two-thirds of the states may call a convention to propose an amendment. To ratify an amendment, three-fourths of the state legislatures must agree to adopt it.
This process ensures that the states have a voice in any changes to the Constitution, and it is designed to be difficult to amend the Constitution, as it has only been done twenty-seven times in over two centuries.
