Answer:
Option C.
Explanation:
The rights of states to deny federal laws they deem unconstitutional, is the right answer.
Nullification, in the constitutional history of the United States, is a legitimate theory according to which state has the power to nullify or revoke, any national law which that state has considered illegal concerning the Constitution of United States (in contrast to the constitution of the state). The doctrine of nullification has never been constitutionally supported by federal courts.
