The McCulloch v. Maryland Supreme Court case firmly established that state governments can overrule the federal government. the federal government cannot tax states. state governments have the same amount of power as federal government. the federal government has more power than state governments.

Not sure what the question is here, but this sounds inaccurate.  The court decided that the Federal Government had the right and power to set up a Federal bank and that states did not have the power to tax the Federal Government. This means the state and Federal gov did not have the same power. Not sure where you got that info, that is incorrect.

D.) the federal government has more power than state governments.
