Answer:
B. It made slave owners in Louisiana and the rest of the South even more fearful of slave revolts, increasing the divide between North and South.
Explanation:
John Brown was an abolitionist leader in America. He viewed rebellion and violence as a necessary element to end slavery in America. After many years of verbal persuasion, Brown considered that now through the means of violence they need to end American slavery. Therefore, on October 16, 1859, Brown led an army of some eighteen men into the small town of Virginia, Harper's Ferry, to seize arms and ammunition. His action led to his execution which in turn led many slavery abolitionists to come into action. This force made slave owners fearful of slave revolts. This also resulted in increased tension between the North and the South.
Therefore, option B is the correct answer.
