B! it’s the only answer that would make sense with the sentence
I believe the answer is C but not 100% sure
The correct answer is Civil rights act
This act prevented states from implementing voter limiting acts which were designed to segregate African-American people. It also had a set of laws regarding segregation in general, as in segregation in employment, education, public life, and any other similar things. Later they added the Housing act which also protected equal housing.
The Constitution enumerates certain powers which are reserved to the federal goverment and other powers which are delegated to the state.
Those powers which are not explicitly related in the document to any of the goverment levels will automatically be reserved to and exercised by the supreme federal goverment.
C because that is the only one that makes sense
