Answer:
D. The plan called for the creation of two states, one Arab and one Jewish, in the mandate.
Step-by-step explanation:
After the end of the British Mandate, the United Nations decided that two states would be created in Palestine, an Arab state and a Jewish state. Only the Jewish people accepted it and they proclaimed the State of Israel in 1948. The Arabs did not accept the plan and war started, the First Arab-Israeli War.
