Answer:

The Civil War legislation helped changed the economy of the nation by (B) the introduction of income tax, the Homestead Act, the granting of land to railroad  companies.

Explanation:

The Homestead act allowed Western immigration by giving 160 acres of public land to settlers. In return, homeowners paid a small deposit fee and before acquiring the land ownership they were required to complete a five-year stay. Homeowners had given the option to purchase land from the government after completing six months of their residence at an acre costs around $1.25 . The Homestead Act resulted in 80 million acres of public distribution.

Also, the granting of land railroad companies allowed the trade of many goods and opened the chance of raw materials to reach factories in the east and all the states, not to mention the high job opportunities, improving by that the growth of the economy.
