What is true of American woen during World War II is that they were instrumental in the war by working in heavy industry - as there were a lot of men who were fighting on the batlefields, it did happend that women had to work in the heavy industry as well. However, it is more likely that they were mostly serving in lighter industry which was easier for them to work in. What was also true was that they could participate in the war effort by serving as nurses - however this wasn't the only case.
You could say that A and D were right.
