The correct answer is B) Congress would not agree on where the line would run.

The first attempts to create a transcontinental road failed in part because Congress would not agree on where the line would run. And there was not much interest of the government for the transcontinental railroad because the issue of slavery and the conflicts between North and South took much of its attention.

It was until the Pacific Railways acts o 1862 and 1864 provided the loans and the land for the construction of the transcontinental railroad that connected the East portion of the country with the West. The Union Pacific built the railroad from Omaha, Nebraska and the Central Pacific built it from Sacramento, California.
