Q. The term ‘D Day’ refers to which of the following events during the WWII?
Answer: The opening of second front in Western Europe
Notes: Even though the Soviet Union- which was already directly fighting the Nazi Germany across Eastern Europe- had been demanding opening of a second front against the Nazi Germany in the Western Europe, allied powers did not agree to it for a few years. Eventually, in June 1944, the Allied troops opened the 'Second Front' in Western Europe. On 6th June 1944, known as the 'D Day', the first allied troops landed on the beaches of Normandy, on the north coast of France. By the end of June, the number of the Allied troops which had landed in France had gone up to 1600000. So, option c is the correct answer.
