The 18th amendment is the prohibition of alcohol and really has nothing to do with women's suffrage. The 14th amendment is gave everyone born or naturalized in the United States equal right, this included slaves. Now the 14th amendment could fool some people this was hardly including women as this amendment really meant all men born or naturalized. The 14th amendment IS the equal rights amendment, so this is just a repeated answer. So want to pick "A. Nineteenth Amendment" because the 19th amendment was passed on June 4th, 1919 guaranteeing all women the right to vote.
