The correct answer is D.
In the 1910s and 1920s the second wave of the Ku Klux Klan emerged. It was originated in Protestant communities and it fought for white supremacy. It mythologized the first Klan from the Reconstruction Era. They also opposed the arrival of Catholic and Jews inmigrants from Europe.
It is true that KKK members used to adopt a pro-Prohibition position, but it was not one of the main goals of the organization at all.
