The correct answer is - B. They were denied independence and divided between British and French mandates.
During the World War I, the Arab countries were fighting against the Ottomans in order to get independence. While they managed to push away the Ottomans, with the help of the British an the French, their initial goal was not accomplished. They did not gained independence, but instead they ended up as being mandates of either the British or the French who split the region in zones of interest. The Arab countries had to wait for a little more time to pass until they finally managed to get full independence and create their own governing systems and proper nations.
