Answer:
D. to reinforce that she is strong, resilient and female
Step-by-step explanation:
In the second paragraph of her famous speech in 1851, Sojourner Truth, counterclaims the statement that "women need to be helped into carriages, and lifted over ditches, and to have the best place everywhere". That implies that women are weaker and not as capable as men. She counterclaims this by stating all the things she has done throughout her life, all the hard work, bearing 13 children, all the pain she was endured.
Repeating this rhetorical question throughout the paragraph is as though as she's asking: "If I'm as week and fragile as you claim women are, how could I've done all these hard things? Ain't I a woman too?"
