Answer:
The correct answer is option C. Slavery is a degrading institution to all those involved.
Step-by-step explanation:
As Douglass narrates, slavery not only degrades slaves, but slavers as well. He tells of all the aberrations that he suffered from the slavers and you can see how those people reach the lowest point that a human being can reach.
Even Sophia Auld, who started out as a kind person and who taught Douglass, ended up being despicable because of the power that being a slave trader brought.
Given this information we can say that the correct answer is option C.
