The correct answer is A. It avoids sentimentality by showing that Douglass was unaffected

Explanation:

The word objectivity refers to the quality of impartiality found in some texts, speeches or similar because they present only facts and do not rely on personal perspectives or judgments. This implies, an objective narrative is one that does not involve the perceptions, beliefs or emotions from the narrator, but only present facts. This can be used to have an effect on the reader as describing events without involving the narrator's feelings or perspectives gives the reader an impartial perspective of the events and makes the reader wonder about the feelings of the narrator towards them.

This is the case of the excerpt from Narrative of the Life of Frederick Douglass  presented in the question, considering Douglass does not give any information about his opinion or feelings while he is taken to a new place to have a new slave owner but he only describes the events from an impartial point of view showing himself unaffected, which makes this narrative objective. The previous ideas mean, the narrator or author uses objectivity to increase the power of the narrative as it avoids sentimentality or expressing any feeling by showing Douglass was unaffected.
