Answer:
Ratification is the correct answer.
Explanation:
A constitution amendment is a modification of the constitution. The constitution is required to pass a special procedure before being amended. Generally, the procedure of the constitution amendment is stringent as compared to ordinary legislation. The constitution amendment is so exacting that very few of the proposals for amendments get passed. E.g In Australia out of 44 proposals only 8 were passed, and in Japan, no proposals have been passed in several decades. In the US the final step in adding an amendment to the constitution is Ratification.
