The answer to this question: In McCulloch v. Maryland, the Supreme Court invoked which provisions of the Constitution, would be: the necessary and proper clause and the supremacy clause.
Explanation:
The McCulloch vs. Maryland case, as a response to the financial crisis of 1819, established two landmarks, when the Supreme Court ruled first, that the state of Maryland did not have the power to tax the National Bank, as it was a federal institution, and therefore, the state did not have the power to interfere in a federal institution, especially when it came to taxing, and second, that the power of the federal government and its institutions superseded those of states. In this instance two provisions were invoked from the Constitution: The Necessary and Proper Clause and the Supremacy Clause, which curtail the rights of states to impose taxes on federal institutions, and also, that establish that the federal government reigns supreme over states.
