During WWII what three companies provided 85 percent of Great Britain's oil supply?

• A. BP, Shell, and Esso
• B. Royal Dutch, Standard Oil, and Gulf
• C. Texaco, BP, and Esso
• D. Shell, Anglo-Iranian, and Jersey

Answer: (D)

The important idea here is how a war economy relies on secure, large-scale energy supplies and how a country without much domestic oil must depend on a small number of international producers that can meet the demand under dangerous conditions. During WWII, Britain faced immense fuel needs for ships, aircraft, tanks, and industry, all while enemy forces tried to cut off supply lines. That made control of oil sources and the ability to move crude and refined products to Britain a strategic priority. Anglo-Iranian Oil Company was central because it operated the Abadan refinery and the Iranian oil fields, giving Britain a vast and relatively reliable source of crude from the Middle East route. Shell contributed through its vast network of oil interests and refineries in the Middle East and elsewhere, providing large volumes of fuel and the infrastructure to get it to Britain and Allied forces. Jersey, though smaller, represented a crucial supplier with established distribution and refining capacity that helped ensure steady deliveries despite wartime disruptions. Together these three controlled the majority of Britain’s oil supply, enabling the Royal Navy, the air force, and the broader war economy to function under the strain of convoy battles, U-boat attacks, and long-range campaigning. Other companies and regions played supporting roles, but the trio that supplied most of the oil had the scale and the logistics to keep Britain running at wartime intensity.
