The correct answer to this question is A, Day-Day. This day occurred on June 6, 1944, and was during the time of World War II. Forces began preparing for this operation the year before in 1943. On this day, the Allied forces invaded the northern region of France.
It did so through the land of Normandy, which is why D-Day is also known as Normandy landings. It is so widely known because it is the largest invasion that happened through the sea in history. In the end, the Allied forces claimed victory, which would also be the result of the War.
The correct answer to this question is option A – Day-Day The term D-day often refers to the day an attack or operation is initiated in military. This term is mostly used to refer to the 6th of June, 1944. It was the day that the Allies invaded Normandy from England during the Second World War. It is believe that the “D” in “D-Day” also stands for “Day” while the French agree that the “D” stands for “Disembarkation”.
Other says “D-Day” stands for Day of Decision”. The day before the D-day is known as “D-1” and the day after the D-Day are known as “D+1” and this goes on. Also, “H-Hour” was used to refer to the start time of the operation. Hope you find this information helpful.
