b. railroad companies rejected workers’ requests for higher wages.
c. railroad companies fired workers who asked for higher wages.
d. railroad companies responded with violence when workers requested higher wages.

The best answer is B.Railroad companies rejected workers’ requests for higher wages.

Railroad workers during the second half of the 19th century were paid very poorly, and in 1873 a financial panic contributed to worsening their economic life. The major rail lines announced cut wages, and in 1877 announced another 10% wage cut, infuriating workers at Martinsburg, West Virginia. They responded by walking off their job and blocking the tracks. This sentiment went viral from Maryland to California with strikes covering hundreds of cities and towns.

the answer is states.
