Answer:
D. Passed laws to slowly end slavery.
Step-by-step explanation:
Northern states successfully ended slavery through state laws, and some leaders hoped the South would do the same.
People in the South supported slavery for three reasons.
1-. Enslaved people made it possible for large farms to grow more crops and make more money. Slaveholders made millions of dollars by growing cotton on plantations.
2-. The invention of the cotton gin made the practice of slavery even more profitable.
3-. Slaveholders even argued that African Americans benefited from being enslaved.
