D) to divide former Ottoman and German territories among Allied Powers
Explanation:
The World War I ended with a win of the Allies. This mean that they also managed to get their hands on the territories that were occupied by the Germans and the Ottomans until then. The territories in question were in the Middle East and in Africa. The Mandate System was practically having the purpose of the Allies to make an agreement as to who will take which territory under their control in the name of the League of Nations, thus dividing the territories in accordance to their interest in a peaceful manner.
The primary purpose of the Mandate System following World War I was to divide former Ottoman and German territories among Allied Powers. These territories included areas in the Middle East, Africa, and the Pacific. The victorious allies argued that it would help prepare those territories for eventual independence, but independence really only came following World War II… and the end of the Mandate System.
