The correct option is A Saint-Germain
Apart from the Treaty of Versaille, Austria-Hungary was asked to sign a separate treaty with the Allied powers, the Treaty of St. Germain. It was signed at Saint-Germain-en-Laye, near Paris, on September 10, 1919. As per the treaty, the Habsburg Empire was broken into independent nation-states. The Austro-Hungarian navy was divided. Austria was not only forced to accept the independence of Czechoslovakia, Yugoslavia, and Poland, but also had to give away some of its territory to them.
