The theory that was used to justify claims of racial superiority was <u><em>social Darwinism.</em></u>
Social Darwinism was a group of ideologies that arose in the late 1800s in which Charles Darwin´s theory of evolution by natural selection, was used to justify certain social views.
According to the theory, the weak were diminished while the strong grew in power over the weak.
One of the persons who adopted social Darwinism was Adolf Hitler, who considered that the German master race had grown weak due to the influence of non-Aryans, so he targeted certain groups of people that he considered biologically inferior for extermination such as jews, homosexuals, etc.

Answer: C. A racist terrorist group founded after the Civil War.
Details:
The Ku Klux Klan began in 1866 in Tennessee as an organization of Confederate veterans of the Civil War. They derived the name "Ku Klux" from the Greek word κύκλος (<em>kuklos) ,</em> which means circle. The group became a resistance movement against radical Reconstruction in the South, seeking to intimidate blacks and restore white supremacy. The group carried out many acts of extreme violence, and acts in Congress and a decision by the Supreme Court <em>(United States v. Harris, </em>1882) went against the Klan. By that time, though, the Klan had mostly stopped operating because it had pretty much achieved its goal: white dominance in the South.
A revived version of the Klan appeared again beginning in 1915, expanding its target beyond blacks to Jews and others. At its height in the 1920s, this revived version of the Ku Klux Klan had more than 4 million members. Today it is a fringe group in the US, with only a few thousand members.
