Answer: B. They filled important jobs in wartime industries.
Step-by-step explanation:
During World War II, around 350,000 women labored in the U.S. Armed Forces. At the same time, since the extensive male war enrollment left the industrial labor force needed of workers, the female percentage of the U.S. workforce rose from 27 percent in 1940 to almost 37 percent by 1945. By then, approximately 25% of American married women worked, often in wartime industries.
