Answer:
The correct answer is D. Shipping goods between the east coast and the west coast was mad easier by the Transcontinental Railroad.
Explanation:
The first Transcontinental Railroad in the United States is the name of a railroad line through the United States that united the city of Omaha with Sacramento in the 1860s, thus uniting the eastern railroad network of the United States with California, on the Pacific coast. In this way, it boosted trade between the different regions of the United States, and encouraged the population of hitherto inhospitable areas, such as the south and west of the country.
As a consequence of the Transcontinental Railroad, the industrial products of the northeast began to arrive to all the country, at the same time that the agricultural products of the south expanded towards the north.
