Which body has the power to propose amendments to the Constitution?

The body that has the power to propose amendments to the Constitution is Congress, which is made up of two houses: the House of Representatives and the Senate. This means that either house can initiate the process of proposing an amendment, as established in Article V of the Constitution.

When an amendment is proposed, it typically requires a two-thirds majority vote in both houses of Congress before it can be sent to the states for ratification. This allowance for both the House and the Senate to propose amendments reflects the framers' intention to ensure a broad consensus is required for constitutional changes, thus making the process thorough and deliberate.

The other choices incorrectly limit the power to propose amendments to one house or suggest that the Supreme Court has this authority, which is not the case. The Supreme Court does not have the power to propose amendments; its role is more about interpreting the Constitution and resolving legal disputes that arise under it.
