Question

californias marijuana law is an example of ___.
nullification
the necessary and proper clause
the elastic clause
devolution

Explanation:

Nullification is when a state rejects a federal law. The necessary and proper clause and elastic clause relate to Congress's powers. Devolution is the transfer of power from a central government to local or regional ones. California's marijuana law, in the context of federal - state relations regarding drug laws, is an example of a state taking a stance different from federal law, but it's not nullification as it's not a formal rejection of federal law in a legal - technical sense. However, among the options, nullification is the closest concept as it involves a state's action in relation to federal policy.

Answer:

nullification
