The correct answer is: "the American Red Cross ".

When the US entered in WWI in 1917, the presence of the American Red Cross  in European battlefields and fronts grew spectacularly and it became the major humanitarian organization that provided medical personnel and supplies on both sides of the war. Many women served in this organization as nurses or assistants, so this was the main manner that they had to contribute in the conflict in the front line.
