The statement that best explains why women's-rights activists were dissatisfied with the Fifteenth Amendment is that " B They felt women should gain the right to vote at the same time emancipated slaves did."
The correct option is B
The Fifteenth Amendment to the Constitution of the United States ('Amendment XV') states that governments in the United States can not prevent a citizen from voting on the grounds of their race, color, or previous condition of servitude (slavery). It was ratified on February 3, 1870.
