The correct option is B Israel
During the First World War, British policy became gradually committed to the idea of establishing a Jewish home in Palestine. After discussions in the British Cabinet, and consultation with Zionist leaders, the decision was made known in the form of a letter by Arthur James Lord Balfour to Lord Rothschild. The letter represents the first political recognition of Zionist aims by a Great Power. The Balfour Declaration stated that the British government supported "the establishment in Palestine of a national home for the Jewish people".
