Final answer:
During World War II, the majority of American women who entered the labor force were married and had children. They filled roles in different industries, particularly in factories manufacturing war materials.
Step-by-step explanation:
The majority of American women who entered the labor force during World War II were married with children (option C). The war led to a manpower shortage as men were recruited for the battlefield. This opened up positions in various industries, especially in factories producing war materials. The icon of Rosie the Riveter was popularized during this time, symbolizing women who worked in war factories. Women were encouraged to join the workforce to compensate for the shortage of male workers. Many of these women were already married and had children, but stepped up to take on additional responsibilities to support the war effort.
