Question

a result of the kansas-nebraska act of 1854 was
the enforcement of
the missouri
compromise. the formation of the
republican party. the elimination of
popular sovereignty. the implementation
of the fugitive slave
act.

Explanation:

The Kansas - Nebraska Act of 1854 repealed the Missouri Compromise, so option A is wrong. It introduced popular sovereignty (so option C is wrong) and the Fugitive Slave Act was part of the Compromise of 1850, not a result of this act (so option D is wrong). The act led to the formation of the Republican Party as opponents of the act united.

Answer:

B. the formation of the Republican Party.
