Question

Which one of the following methods was used only once to ratify an amendment?

A. By approval of conventions in three-fourths of the states
B. By approval of the Supreme Court
C. By approval of three-fourths of the state legislatures
D. By approval of the President

Answer 1

By approval of conventions in three-fourths of the states

Step-by-step explanation:

Congress decides which method of ratification should be used. In fact, the convention method of ratification was used only once.

Answer 2

The correct answer is A. By approval of conventions in three-fourths of the states

The most common way is the third one, three-fourths of state legislatures and a supermajority of the congress approves it, however, only once the first method was used. It is a legitimate option outlined in the constitution. The congress can call for national conventions which can pass the amendment but this doesn't happen often.
