Final answer:
The conflict in the excerpt from 'Narrative of Sojourner Truth' is between Bell and her master Dumont, regarding her enslavement and broken promises of freedom.
Step-by-step explanation:
The correct answer is option D. Bell is in conflict with Dumont over her enslavement. In the excerpt from Narrative of Sojourner Truth, the external conflict described involves Bell firmly standing up to her master, Dumont, who demands her return after she left without his permission.
She justifies her departure by pointing out that he had previously promised her a year of her own time, which he now refuses to honor. Instead of complying with Dumont's command to return, Bell asserts her own will, demonstrating her resolve against the oppressive institution of slavery that seeks to control her life.
