Which of the following best describes the outcomes of Nat Turner's Rebellion?

The correct choice highlights that Nat Turner's Rebellion significantly heightened the anxieties and fears of slaveholders throughout the South. Occurring in 1831, Turner's uprising resulted in the deaths of approximately 60 white individuals and instilled a potent sense of vulnerability among slave owners who worried about similar revolts. This fear led to stricter slave codes, increased patrols, and a more aggressive stance on maintaining the institution of slavery, as slaveholders sought to prevent future uprisings and ensure their control over enslaved populations.

While the rebellion did raise national awareness about the brutalities of slavery, it did not lead to an immediate abolition of the institution or widespread emancipation movements at that time. Rather, it resulted in more oppressive measures rather than improvements in the conditions for enslaved people. Thus, option B aptly encapsulates the immediate impact of Nat Turner's Rebellion in the context of rising tensions and fears surrounding slavery in America.
