Answer:
D is the correct option.
Step-by-step explanation:
Dwight Eisenhower served as the Supreme Allied Commander in Europe. The term supreme allied commander originated during the first world war. The first supreme allied commander was Ferdinand Foch, who commanded French, British and Italian forces during world war one. During the second world war, the allies appointed supreme allied commanders for their multi-nation armies. Full operational control to Land, Air, and Sea units was given to them. Eisenhower served as the Supreme Allied Commander for the Mediterranean theatre. Later he held the same post for NATO forces.
