The correct answer is alternative D) "Helping poor women and children".
At the beginning of the 20thcentury women still didn't have the right to vote in the United States of America. Their pursuit for women's suffrage began in the 1840s but only achieved its goal in 1920.
They claimed women cared more than man about helping poor women and children. They found themselves more sensitive and caring of those who needed it the most, other minority groups like them, etc.
