The case proved that the states cannot challenge the implied federal powers
The correct answer is: "The case proved that the states cannot challenge the implied federal powers".
McCulloch vs. Maryland was a landmark decision enacted by the US Supreme Court in 1819 and it established that, according to the "necessary and proper clause" included in the US Constitution, the federal goverment holds certain implied powers that are not explicitly listed but that it can exercise over the state legislations, as the federal goverment is always supreme over the states.
