Answer:
Option C, When a strike threatens the public welfare, the federal government is expected to step in, is the right answer.
Explanation:
A strike launched in the anthracite coalfields of eastern Pennsylvania by the United Mine Workers of America is known as the Coal strike of 1902. The main issues of the miners included shorter workdays, raised wages, and the recognition of their union. For the accomplishment of their demand, the strikers threatened the administration to shut down the fuel supply to the major cities of America during the winter season.
Theodore Roosevelt, the then U.S. President intervened in the strike on 8th June 1902 by ordering Carroll D. Wright, his Commissioner of Labor, to investigate the strike. He justified his intervention by asserting that "when a strike endangers the welfare of the people, the federal government is required to move in".
