Answer:
B
Step-by-step explanation:
B. The legal status of slavery in the new territories is the issue that created conflict between the North and the South when Kansas and Nebraska were added as territories.
The Kansas-Nebraska Act of 1854 allowed the territories of Kansas and Nebraska to decide for themselves whether or not to allow slavery. This effectively repealed the Missouri Compromise of 1820, which had prohibited slavery north of the 36°30' parallel.
This issue created conflict between the North and the South because the North believed that slavery was immoral and should be banned everywhere, while the South believed that slavery was necessary to their economy and way of life. The North saw the Kansas-Nebraska Act as a betrayal of the Missouri Compromise and an attempt by the South to expand slavery into new territories. This led to violence and bloodshed in Kansas, as pro-slavery and anti-slavery settlers fought for control of the territory.
A is not the correct answer because the representation in Congress was not the primary issue of conflict. The North and South were already divided on the issue of slavery, and the Kansas-Nebraska Act did not significantly alter the balance of power in Congress.
C is not the correct answer because the geographic size of the territories was not a major issue of conflict. Both the North and the South were interested in expanding their territories, but the issue of slavery was more important to them.
D is not the correct answer because the power of local governments in the territories was not the primary issue of conflict. While there were disagreements over the structure of local government in Kansas, the primary issue was the legal status of slavery in the territory.
