D) The NWSA worked for a constitutional amendment granting suffrage; the AWSA fought for suffrage at the state level.
Explanation:
The National Woman Suffrage Association, NWSA was created on May 15, 1869 in New York. It was created after a break with the American Association for Equal Rights for the debate over whether the women's movement should support the Fifteenth Amendment to the United States Constitution. Its founders, Susan B. Anthony and Elizabeth Cady Stanton, opposed the Fifteenth Amendment unless it included the vote for women. Men could participate in the organization as members but could not assume leadership. The NWSA worked to incorporate women into the federal constitutional amendment. Contrarily, his rival, the American Association for the Suffrage of Women (AWSA), led by Lucy Stone, considered that success would come more easily through state-by-state campaigns. In 1890 the NWSA and the AWSA merged to form the American Association for the Suffrage of Women (NAWSA).
