The correct response is:
Women could serve in auxiliary military organizations that took over work done by men who were sent overseas to fight.
During World War II, women took on more varied and significant roles in the military, including serving in auxiliary organizations such as the Women's Army Corps (WAC) and the Navy Women's Reserve (WAVES), allowing them to participate in a wider range of military activities compared to World War I, where women's roles were more limited to nursing and support positions.
