Final answer:
The issue addressed by McCulloch v. Maryland was taxes imposed on banks that were not chartered by the state. The Supreme Court ruled that the state did not have the power to impede the legitimate actions of the federal government. The correct answer is option B.
Step-by-step explanation:
The issue addressed by McCulloch v. Maryland was the question of whether the federal government had the authority to establish a national bank and if states had the power to tax such a federal entity. The state of Maryland imposed taxes on the Second Bank of the United States (BUS), a federally-chartered bank, to favor state-chartered banks. The Supreme Court, under Chief Justice John Marshall, ruled in favor of the BUS. It declared that Congress had the authority to create a national bank under the "necessary and proper" clause of the Constitution and that states could not tax federal institutions as it would imply state supremacy over federal actions, contrary to the supremacy clause of the Constitution.
