Answer:
C. The Supremacy clause
Explanation:
The supremacy clause stated that in case there is a conflict between the state legislation and the Federal legislation, the federal legislation will always overpower the state legislation.
From the case above:
- Brad obtains a permit from the Federal government to fish in that area.
- The State banned Brad to fish in that area.
By contradicting the Feds, California actually violates the supremacy clause. Brad should've been allowed to fish in that area.
