Correct answer choice is :
D) 618,000
Step-by-step explanation:
Approximately 1,264,000 American soldiers have died in the nation's wars 620,000 in the Civil War and 644,000 in all other battles. It was only as late as the Vietnam War that the number of American deaths in different wars surpassed the number who died in the Civil War. The number that is most frequently quoted is 620,000. At any rate, these losses pass the nation's loss in all its other wars, from the Revolution through Vietnam.
