The mcculloch v. maryland supreme court case firmly established that

a. state governments can overrule the federal government.
b. the federal government cannot tax states.
c. state governments have the same amount of power as federal government.
d. the federal government has more power than state governments.

The correct answer is D.

The McCulloch v. Maryland was a Supreme Court decision issued in 1819 which established that the "necessary and proper clause" included in the US Constitution, grants the federal government certain implied powers which are not mentioned explicitly.

In that specific case, the state of Maryland tried to block an operation of the Second Bank of the United States. The court invoked the necessary and proper cause to justify the intervention of the federal goverment. This decision was also crucial in the sense that is established the boundaries between the state and the federal powers, which were unclear until that moment.
