Correct answer choice is :
B) Formed the republican party.
Explanation:
Anti-slavery Whigs had started meeting in the upper midwestern states to explain the production of a new party. One such meeting, in Wisconsin on March 20, 1854, is usually recognized as the founding meeting of the Republican Party. The Democrats and Whigs were clearly distributed over the slavery issue, and their power efforts made the way for the rise of a new political party, the Republican Party, which was established in 1854 and stood united in their decision to stop the spread of slavery into the territories and defend the Union.
