It seems that the answer options you've provided are incomplete. However, based on your question, if we were to compare the rhetorical devices typically used in the two works mentioned:
-
"Ain't I a Woman?" by Sojourner Truth often employs rhetorical questions to emphasize her arguments about race and gender, directly engaging her audience and provoking thought.
-
The Declaration of Sentiments, which echoes the style of the Declaration of Independence, frequently uses allusion to historical documents and principles, as well as enumeration to list grievances and demands for women's rights.
Given this understanding, the most accurate comparison would probably be that "Ain't I a Woman?" employs rhetorical questions, while the Declaration of Sentiments uses enumeration and allusion.
