<em>Answer:</em>
B) African Americans gained more rights and influence in society
<em>Explanation:</em>
Well, first, you need to know what the KKK was/is. The KKK was a group of white people who used violence against black people because of their racist ways.
Next, you need to look and the answers and find the answers that would obviously be against black people. In this case, we can eliminate answers A and D.
Now we only have B and C to look at. Let's look at C first: The Freedmen's Bureau was created in March of 1865, while the KKK was founded in December of 1865. While it may be possible this was the cause, it is unlikely because of how far apart the dates are. Now let's look and B: Although the Freedmen's Bureau was created in March of 1865, it may have took a little bit for African Americans to start to gain more rights and influence. Once the KKK started to realize that they were gaining rights, they founded their clan and begun to use violence to stop this. :)
