Living in the desert is the answer, because the location does not cause conflicts (unless you count borders, which I’ll bring up why).
Here are why the other reasons are right:
Oil has caused many conflicts within the Middle East, because it is a valuable resource and can enrich a nation. One example of this is the Iraqi invasion of Kuwait. Part of it was oil related, which disproves tu is as an answer.
Borders also have caused conflicts. Because of the colonialism within Africa and the Middle East, it has caused many disputes about borders. Not an example of former colonialism, but the Iraqi-Iran war involved the border (and Iraqi nationalism), which makes this an incorrect answer.
Arab Spring is a major example of conflict, since it has caused many demonstrations within Arab nations against government authoritarianism/oppression, and has even caused civil war to occur.
Finally, religion has caused many conflicts. One big example of this is the Israel-Arab wars, and conflicts between the Shia government of Iran and the Sunni government of Saudi Arabia (not wars, but foreign relations and involvement in proxy wars)
Hope this helps!
