Final answer:
Harriet Tubman's hesitancy in assisting John Brown likely stemmed from concerns about his preparedness and the potential violence of his plans, influenced by her own strategic approach to abolition and knowledge of past uprisings.
Step-by-step explanation:
The hesitancy of Harriet Tubman in assisting John Brown likely stems from her concern about the level of preparedness and potential violence associated with his planned revolt. Tubman was known for her strategic and careful approaches to conducting Underground Railroad missions, which often contrasted with Brown's more radical and less meticulously planned actions. Brown was passionate about abolition but his approach, culminating in John Brown's raid on Harpers Ferry, was extreme and not universally supported within the abolitionist community.
Tubman's own experiences and knowledge of history, including previous violent uprisings such as Nat Turner's Rebellion, could have also made her wary of the consequences of a poorly-executed revolt. Option B is correct .
