D) Elevating the cause of women’s rights to an issue of national concern.
Explanation:
The Seneca Falls Convention was held in New York, on January 19 and 20 1848.
Because of the feminists like “Elizabeth Cady Stanton” and “Lucretia Mott” this convention was the first convention organized by women to discuss the rights to vote, and with that topic.
Frederick Douglass, a former slave who was later granted the freedom he wanted, but who still suffered severe and unfair segregation was given an opportunity to speak.
This convention became an achievement of a breakthrough in women's right to vote 70 years later.
