Answer:
C. To appeal to an audience that is against slavery.
Step-by-step explanation:
Susan B. Anthony believed that the feminist movement and the fight for suffrage was a movement for liberation. It would allow women to be their own masters and reach their highest potential. However, she knew that not everyone in the audience was convinced by this argument. Anthony decided to draw some parallels between this fight and the struggle of black people in an attempt to convince those who supported black people, but were unsure about the feminist movement.
