Answer:
E: Kansas-Nebraksa Act
Step-by-step explanation:
Due to prejudice, discrimination, systematic racism, and sexism, black people and women have historically been denied the right to equal protection under the law. While laws like the Kansas-Nebraska Act and judicial rulings like the Dred Scott decision both contributed to the continuation of inequality, they were ultimately just the outward signs of more pervasive societal prejudices. On the other hand, those who believed in white supremacy and the subjection of Black people opposed abolitionists' and the Underground Railroad's attempts to abolish slavery and advance equality for Black people.
