amending the constitution
proposed
amendment is proposed by a two - thirds vote of each house of congress
amendment is proposed by a national convention called by congress at the request of two - thirds of the state legislatures.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: A three - fourths vote in the Senate is for ratification, not proposal by Congress, so A is incorrect.
• Option B: Two - thirds of state legislatures can call for a national convention to propose amendments, not for Congress - proposed amendments, so B is incorrect.
• Option C: A national convention is another way to propose amendments, not the way Congress proposes them, so C is incorrect.
• Option D: According to the process of amending the US Constitution, for Congress to propose a constitutional amendment, it requires a two - thirds vote of each house (House of Representatives and Senate) of Congress. The diagram also supports this as it shows "Amendment is proposed by a two - thirds vote of each house of Congress".

Answer:

D. a two - thirds vote of each house of Congress.
