Answer 3

You are correct. B and C must be incorrect, since railroads encouraged expansion rather than just focused on one part of the US. C is also incorrect since the competition would have increased, since prices are reduced from the efficiency of railroads. D is nonsense since the purpose of railroads was not for people to change occupation, it's main goal was for transportation of goods (economic) and people.

A is the only answer that demonstrates the main idea of railroads and their economic benefit for companies
