Civil rights activists challenged southern voting laws because they conflicted with the fifteenth amendment. the civil rights act of 1964. the emancipation proclamation. the declaration of independence.

The correct answer is:  the Fifteenth Amendment.   The main purpose of the fifteenth amendment was to grant the right to vote of the former slaves, for it states are prohibited from using the race of a citizen, the color or the previous state as a slave to restrict their vote. However, in some states, black voters and white republicans continued to be intimidated.  

the punishment for breaking the law would depend on the conditions or the seriousness of the law being broken, if he or she breaks the law while doing some great discovery or invention then it would classify as a scientific fraud. there are other words to describe the crime but scientific fraud would be the harshest one.
