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 not explicitly stated in the Constitution but are considered necessary to carry out the government’s expressed powers. The establishment of the Bank of the United States is an example of implied power because it helps Congress execute its power to regulate commerce and manage currency, even though the Constitution does not specifically grant Congress the power to create a bank. This concept is rooted in the Necessary and Proper Clause of the Constitution.
