The correct answer is A) declaring Nebraska to be free territory.
The Kansas-Nebraska Act of 1854 contained all of the following provisions, except declaring Nebraska to be a free territory.
The Kansas-Nebraska Act contained the creation of two new federal territories, repealing the antislavery provision of the Missouri Compromise, allowing voters and territorial legislatures to decide the slavery issue for themselves, and creating popular sovereignty as a method of compromise.
The basic element of the Kansas-Nebraska Act was that this legislation allowed people to decide if slavery was going to be authorized in the state. This created more and more confrontation between the northern and the southern states to the degree of being one of the causes that started teh American Civil War.
