Answer:
Option B. The Caning of Senator Charles Sumner
Explanation:
The question asks for an example of tension between the North and the South <u>before</u> the Civil War.
Thus, option A) is ruled out because it was the first major battle of the Civil War. Option C) is also incorrect because the Emancipation Proclamation is from 1863 (the Civil War had started in 1861) and option D) cannot be correct given that the assassination of Lincoln took place after the Civil War had ended.
It is option B), The Caning of Senator Charles Sumner the correct answer. Preston Brooks, a pro-slavery Democrat used a cane to attack Charles Sumner an abolitionist Republican the 22th May of 1856,<u> before</u> the Civil War; exacerbating the tensions between pro-slavery and abolitionist forces.
