b. they families control local markets and materials.

c. they allowed businesses access to markets farther away.

d. they to increase profits for small businesses.

I would say C. They allowed businesses access to markets farther away.

Explanation:

Railroads were often used for long distances, as if you lived close by you could just use wagon or horseback. Answer choices A and B uses "nearby" and "local", which was usually not true of railroads. Answer choice D could be an answer but I'm not too sure.

The correct answer is C) They allowed businesses access to markets farther away.

Railroads changed American business in that they allowed businesses access to markets farther away.

Without any doubt, railroads changed life in the United States. Railroads vastly improved transportation conditions and reduced the time when traveling. People could travel safer between long distances and could send more and heavier products through the train. In 1892, with the passing of the Pacific Railroad Act, the federal government authorized the construction of the Transcontinental Railroad that connected the East of the US with the Pacific West. This represented a major change in transportation and improved  trade in America.

i would say your answer would be the second option.

hope this !
