Which scenario is avoided because the constitution contains the supremacy clause

A - one branch of government becomes more powerful then others

B - the federal government amends the constitutions expand citizenship rights to a new group

C-it becomes unclear whether transportation is the responsibility of federal government or a state govern

D - a state passes a law that contradicts the nineteenth amendment

D - A state passes a law that contradicts the nineteenth amendment

Explanation:

The Supremacy Clause, found in Article VI of the U. S. Constitution, establishes that federal laws are the supreme law of the land and therefore all states, federal officers and judges are bound by them, meaning that in case of a conflict between state and federal laws, federal laws are the ones that shall prevail.

Because of the existence of this clause, the states know their limits: they are aware that federal law takes preference over state law, therefore, so it is unlikely that a state decides to pass a law contradicting the 19th Amendment.

The correct answer is D) a state passes a law that contradicts the nineteenth amendment.

The scenario that is avoided because the Constitution contains the supremacy clause is "a state passes a law that contradicts the nineteenth amendment."

You can find the supreme clause in Article VI, clause 2, of the United States Constitution. In simple terms, it says that the laws that appear in the Constitution are the supreme law of the nation. So federal laws take priority when conflicting with any state laws. In a few words, when in conflict, federal laws remain. That is why the scenario that is avoided because the Constitution contains the supremacy clause is "a state passes a law that contradicts the nineteenth amendment."
