a. Middle East ← correct
b. Asia Pacific
c. North America
d. Europe and Eurasia
e. None of the above
Answer: (a). The Middle East (led by Iran and Qatar's share of the giant offshore South Pars/North Field structure, plus Saudi Arabia) has historically held roughly 40% of world proved conventional natural gas reserves, more than any other single region; Europe and Eurasia (chiefly Russia) is the next-largest bloc, followed at a considerable distance by Asia Pacific, North America and the rest of the world. This reserves concentration reflects the handful of supergiant fields (South Pars/North Field alone accounts for a large share of the total) that dominate the world gas resource base, and it is a very different distribution from gas PRODUCTION, where North America and Russia have historically led.
