Final answer:
Establishing the Bank of the United States is an example of an implied power of Congress because it falls under the Necessary and Proper Clause, allowing Congress to execute its enumerated powers.
Step-by-step explanation:
The question asks which action is an example of an implied power of Congress. Among the options provided, establishing the Bank of the United States is an implied power. This is because the Constitution does not expressly list the creation of a national bank as a power of Congress. Instead, it falls under the Necessary and Proper Clause, which allows Congress to pass laws needed to execute its enumerated powers effectively. Therefore, the creation of the Bank of the United States is an action that represents an exercise of Congress's implied powers.
