Final answer:
Sojourner Truth shared personal details in her 'Ain't I a Woman?' speech to highlight the injustices faced by enslaved women and mothers (Option B), aligning with her efforts to promote the acknowledgment of Black women's struggles within the women's rights movement.
Step-by-step explanation:
Sojourner Truth shared details of her hard work, the physical abuse she endured, and the heartbreak of her children being sold into slavery to address why these personal experiences were significant to her speech 'Ain't I a Woman?' at the Women's Rights Convention in Akron, Ohio, in 1851. The most accurate response is B) By sharing these details, she aims to highlight the injustices faced by enslaved women and mothers. This reasoning aligns with Truth's intentions to challenge the prevailing notions about the rights and priorities of men and women within the abolition movement, and to insist upon the acknowledgment of Black women's unique struggles in the quest for women's rights.
