The correct option is B Dissolving the Ottoman empire
The Treaty of Sevres was one of a series of treaties that the Central Powers signed after their defeat in World War I. The treaty was signed on 10 August 1920, in Sevres, France. The Sevres treaty marked the beginning of the partitioning of the Ottoman Empire and its dismemberment.
The terms of the Treaty of Sevres were harsh and many in the Ottoman Empire were left angered and embittered by their treatment. Britain and France had already decided what would happen to the area generally referred to as the Middle East. Britain took effective possession and control of Palestine while France took over Syria, Lebanon and some land in southern Anatolia. East and West Anatolia were declared areas of French influence. This had already been decided some three years before the Treaty of Sevres in the secret Sykes-Picot Agreement of 1917.
