British policy towards Palestina during the first half of the 20th century was:
B.The British promised bth Palestinian and Jews an independent homeland in the same part of its Middle Eastern empire, leading both groups to feel that they had a legal right to the territory.
In the McMahon–Hussein series of letters, the British promised, during the WWI, to recognize Arab independece after the war in exchange of the launching of the Arab revolt against the Ottoman Empire. But in 1917, the Balfour Declaration was realesed stating "a national home to Jewish people" in Palestine. Both nations until now belive they have the right over the territory.
