Who were prominent leaders in the movement for women's rights?

The correct choice highlights the significant contributions of Elizabeth Cady Stanton, Susan B. Anthony, and Lucretia Mott to the women's rights movement. Elizabeth Cady Stanton was a leading figure in the early women's rights movement, known for her role in organizing the Seneca Falls Convention in 1848, where the Declaration of Sentiments was presented, demanding equal rights for women, including the right to vote. Susan B. Anthony worked closely with Stanton and was instrumental in campaigning for women's suffrage. Lucretia Mott, also a key figure in the movement, participated alongside Stanton and Anthony in advancing women’s rights and was a well-known abolitionist as well. Together, these three women formed a powerful trio that laid the groundwork for future advancements in women's rights in America.

The other leaders mentioned in the other choices had their own significant roles in both the women's rights movement and other social justice causes but did not collaborate in the same way on foundational aspects of the women's rights movement as Stanton, Anthony, and Mott did. This context highlights why option C is the most appropriate answer to the question about prominent leaders in the movement for women's rights.
