The correct option is D The Luftwaffe won the battle against the Royal Air Force Fighter Command.
The Battle of Britain was the successful defence of Great Britain against destructive air raids conducted by the German air force, known as the Luftwaffe. From 10 July to 31 October 1940, England and Germany battled for control of the airspace over Great Britain, Germany and the English Channel. The British radar stations were able to give warnings of the approaching German attackers, because of which the Royal Air Force Fighter Command won the battle against the Luftwaffe.
