The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Many Arabic people felt betrayed by Great Britain because they were led to believe that Great Britain would prevent the creation of a Jewish home state as a result of their support in the war.
However, this bever happened, And it is correct to say that many Arabic people felt betrayed when the government of England issued the Balfour Declaration on November 2, 1917.
It was the last year of World War I, when Great Britain issued the declaration to establish an official territory for the Jews in the lands of Palestine, in that moment it was a territory occupied by the Ottoman Empire.
Of course, this decision infuriated teh Arab people and initiated a series of permanent conflicts and wars between Jews and Palestinians.
