The best logical conclusion that Sojourner Truth deduces in this passage is:
B. If men aren't helping her into carriages and she's a woman, then they must be looking at her race with rejection.
This statement aligns with her argument that the treatment she receives as a Black woman reflects both race and gender discrimination. Throughout her speech, she emphasizes her strength, resilience, and right to equality, challenging the assumptions made by white men about the capabilities and rights of women, particularly Black women. She uses her personal experiences to illustrate the broader social injustices faced by both women and Black individuals.
