B.) The courts and national leaders made a variety of attempts to resolve the issue of slavery in the territories, including the Compromise of 1850, the Kansas- Nebraska Act, and the Dred Scott decision, but these ultimately failed to reduce conflict.
California was added as a free state. Due to this, the Compromise of 1850 was passed.

C: The Second Party System ended when the issues of slavery and anti-immigrant nativism weakened loyalties to the two major parties and fostered the emergence of sectional parties, most notably the Republican Party in the North.
By the 1850s most Democratic party leaders had accepted many Whiggish ideas, and no one could deny the economic modernization of factories and railroads was moving ahead rapidly. The old economic issues died about the same time old leaders like Calhoun, Webster, Clay, Jackson and Polk passed from the scene. New issues, especially the questions of slavery, nativism and religion came to the fore. 1852 was the last hurrah for the Whigs; everyone realized they could win only if the Democrats split in two. With the healing of the Free Soil revolt after 1852, Democratic dominance seemed assured. The Whigs went through the motions, but both rank and file and leaders quietly dropped out.
