Answer:
D. The Ku Klux Klan gained power and influence after Southern states lost their statehood under Congressional Reconstruction.
Step-by-step explanation:
The Ku Klux Klan emerged and empowered itself from the disempowerment of southern states during the reconstruction of the south. As these states were totally at the mercy of the Republicans, the Klan established itself as a resistance group, which would do justice with its own hands and promote the destruction of what the Northern Republicans had established, such as the freedom of blacks and the dominance of northerners in the southern territory.
