B Is your answers to the question
50 states are in the united states.
Answer:
This correct answer is a.
Explanation:
Though states can pass laws which apply locally, the Federal government has the final say when there is a conflict between a Federal and a State law. The supremacy clause, article VI of the constitution, says that any Federal law that prohibits a certain practice supersedes any kind of state law. For example, if the state law permits the use of marijuana but the federal law issues a prohibition, the state should comply with the federal law or the federal government can stop the state legislation.
