Answer:
B. It increased federal authority by invoking the doctrine of implied powers.
Explanation:
McCulloch v. Maryland was a litigation or court case between the national bank known as The Second Bank of the United States and the state of Maryland with respect to the tax that was imposed on it by the state.
Basically, the state of Maryland passed a legislation to impose taxes on banknotes ($15,000 annually) of any bank that isn't chartered in the state of Maryland.
However, James W. McCulloch who was head at the Baltimore branch of the Second Bank objected and refused to pay the tax. Consequently, the appellate court of Maryland ruled that the Second Bank was established unconstitutionally because the federal government isn't provided a textual commitment by the constitution to charter a bank.
The Chief Justice of the Supreme Court, Marshall ruled that the Federal government of USA has certain implied powers accorded or given to it by the Necessary and Proper Clause of the Constitution but aren't explicitly stated therein.
<em>Hence, the statement which is true of John Marshall's decision in McCulloch v. Maryland is that, it increased federal authority by invoking the doctrine of implied powers.</em>
