a. it ratifies amendments.
b. it proposes and passes amendments.
c. it has no formal role in the process.
d. it declares amendments constitutional.

The answer is "B. It proposes and passes amendments."

At the point when an amendment to the constitution is proposed, it must be passed by the two houses of the Congress by a two-thirds majority. At that point it proceeds to be passed by either the lawmaking bodies or traditions in the states, where it must be sanctioned by 3/4 of them. A second technique (never utilized) is to get 2/3 of the lawmaking bodies of the states to require a protected tradition at which at least one alterations are proposed. Whenever passed, all changes from this tradition would then must be passed by 3/4 of the state governing bodies or traditions once more. The convention technique has never been utilized to propose an alteration. It has been utilized to sanction one, which was the 21st Amendment, revoking the eighteenth Amendment, which was national restriction.
