The question given above is incomplete, the complete version is given below:
Historical Context: Ratified on February 3, 1870, the Fifteenth Amendment to the US Constitution gave all African American men the right to vote. Many suffragists who had participated in the abolition movement felt betrayed because the right was extended only to men. They had hoped that universal suffrage among African Americans would pave the way for all women to gain the right to vote as well.
A. Anthony suggests that the Fifteenth Amendment will remain powerless unless women are excluded from the classes and races under it.
B. Anthony suggests that the Fifteenth Amendment will remain a sham unless African American women are also extended the right to vote.
C. Anthony suggests that women are superior to African American men and are more deserving of the rights and duties under the Fifteenth Amendment.
D. Anthony suggests that since the plight of women is like that of formerly enslaved African American men, women are entitled to protection under the Fifteenth Amendment.
E. Anthony suggests that since women were the greatest supporters of the abolition movement, it is unfair to deny them the right to vote.
ANSWER
The correct option is D.
Looking at the passage given above, what Anthony is trying to say is that, since both the men and the women of African American origin, who are former slaves share the same plight, then the 15th amendment is applicable to the women also just as it applies to men.
