Which action is an example of an implied power of Congress?

The correct answer is B. establishing the Bank of the United States.

Explanation: Implied powers are those not explicitly stated in the Constitution but are necessary to carry out the government’s enumerated powers. The establishment of the Bank of the United States is an example of an implied power because it was justified through the Necessary and Proper Clause (Article I, Section 8) to help Congress manage finances and regulate the economy, even though the Constitution does not specifically authorize a national bank.
