The correct answer is C. The Middle East.
The Middle East is home to the largest proven oil reserves in the world, accounting for about 65% of the world’s total. The region’s oil reserves are concentrated in a few countries, including Saudi Arabia, Iran, Iraq, Kuwait, and the United Arab Emirates.
Siberia is a region in Russia that is also home to significant oil reserves. However, Siberia’s oil reserves are much smaller than those of the Middle East. The Gulf of Mexico and Caribbean are also home to significant oil reserves, but these reserves are much smaller than those of the Middle East and Siberia. Indonesia is a country in Southeast Asia that is home to some oil reserves, but these reserves are much smaller than those of the Middle East, Siberia, and the Gulf of Mexico and Caribbean.
The Middle East’s oil reserves are a major source of wealth and power for the region’s countries. The region’s oil reserves have also been a source of conflict, as countries have competed for control of these resources.
