Which of the following shows the correct order of events?

Some Western states granted women the right to vote before the national suffrage campaign reached its final stage. Carrie Chapman Catt introduced her “Winning Plan” in 1916 to coordinate the campaign for a constitutional amendment. The Nineteenth Amendment, which prohibited denying the vote on the basis of sex, was ratified in 1920, so the correct order is suffrage in some Western states, Catt’s “Winning Plan,” then the amendment.
