Hi there! I think answer C is the most likely option.
Explanation:
In a sense, all of the options <em>were</em> accurate to the suffering of African Americans, but option C involves the mentioning of not giving up hope. The poem speaks of an African American that had been through all of the horrors of slavery, but they having not given up. At the very end, they mention "mighty mountains" looming before them, signifying that there is a world out there once they escape.
