Correct option is D
In the Middle East, Saudi Arabia is the leading producer of petroleum, followed by Iraq. Kuwait is known for its substantial oil reserves and production capacity, ranking just after Iraq. Iran, while having significant oil reserves, has faced production limitations due to various factors such as international sanctions and infrastructure issues, placing it lower on the list among these countries. Therefore, the correct sequence in descending order of petroleum production in the Middle East is: Saudi Arabia, Iraq, Kuwait, Iran. Hence, the answer is "(d) Saudi Arabia, Iraq, Kuwait, Iran."
