Answer: B.
Explanation: The KKK was a vehicle for white southern resistance to the Republican Party’s Reconstruction-era policies aimed at establishing political and economic equality for blacks. Its members waged an underground campaign of intimidation and violence directed at white and black Republican leaders. It achieved its primary goal which was the reestablishment of white supremacy, fulfilled through Democratic victories in state legislatures across the South in the 1870s.
The Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States which were enacted in the late 19th and early 20th centuries by white Democratic-dominated state legislatures after the Reconstruction period. The laws were enforced until 1965 and they mandated racial segregation in all public facilities in the states of the former Confederate States of America and other states. Although the goals were similar, it wasn't the kkk that started the jim crow laws.
