What Was the Haymarket Riot of 1886

What was the Haymarket Riot of 1886?

A) It was a fight for child labor rights started by the Knights of Labor and, because so many people were sympathetic toward children, improved public opinion of unions in general for years to come.
B) It was an insurrection led by miners that evolved into a productive meeting between workers and management, ushering in an era of improved relations in industries across the nation.
C) It was a days-long demonstration for railroad workers' rights that angered the government, but because it remained peaceful in nature, none of the events' leaders could be prosecuted.
D) Occurring amid a strike in favor of the eight-hour workday, it was what journalists called America's first terrorist bombing and was blamed on anarchist leaders despite a lack of evidence.
E) Primarily a demonstration for African American rights in the workplace, it resulted in government officials emerging as martyr figures, as several of them got hurt trying to stop the demonstrators.
