Who was the queen of England during World War 2?

There was no Queen as such reigning as the British monarch. The ruler during World War 2 was King George the Sixth, the father of the present queen, Elizabeth the Second. However, her mother (also called Elizabeth) the wife of King George, was also called Queen Elizabeth because in British Law, the wife of the King can be called 'queen' although ahe is not reigning in her own right. However, the reigning queen, Queen Elizabeth, cannot call her husband 'king'. Instead he is bestowed with another title. In the case of the present Queen Elizabeth, her husband is a prince in his own right (a prince from the royal fay of Greece), but had the title of Duke of Edinburgh bestowed on him when he married the queen.
