Letter D is correct.
In the early 1900s, women didn't have many work related roles. At that time, most women were homemakers while a very few of them were nurses, teachers, maids and doctors. When women started having more time for leisure, they created women's clubs where they could share ideas and act on them.
In the late 1800s and early 1900s, putting women in school was part of women's club agendas. They believed education was the answer for most society issues, such as chid labor, juvenile delinquency, and lynching.
