Answer:
A) The creation of the State of Israel, which displaced the Palestinian majority
Step-by-step explanation:
The Arab–Israeli conflict refers to the ongoing conflict between Arab countries and Israel. At the end of the 19th century, a rise of Zionism and Arab nationalism was noticeable. That's considered to be the root of the problem, although the situation escalated decades later. An important part in the conflict played a disagreement regarding the land. Both Jewish people and Arab Palestinians considered the territory in question to be their own because of religious and cultural reasons.
On 14 May 1948, when the British rule in Palestine came to an end, David Ben-Gurion, the head of the Jewish Agency, declared the establishment of the independent State of Israel. That same day began the Arab-Israeli War of 1948, as the armies of Egypt, Lebanon, Syria, Jordan, and Iraq invaded this territory.
