Respuesta :
Stephen Douglas wanted the Kansas-Nebraska Territory organized because he wanted a transcontinental railroad with a route through the territory. This movement would very much benefit Douglas' Illinois constituents as well as for him to maintain civic-control towards such territory. Southern senators objected such proposal, hence the area was deemed as a free-state.
The correct answer is : Option B, he wanted a transcontinental railroad with a route through the territory.
Just got it correct:) Have a great day!
