Which of the following is a power granted to Congress?

The power granted to Congress that is highlighted in this situation is the ability to levy taxes. This authority is explicitly stated in Article I, Section 8 of the U.S. Constitution, which outlines the enumerated powers of Congress. Taxation is a fundamental power that allows Congress to raise revenue for the federal government to fund its operations and obligations.

In contrast, creating international treaties is a power granted primarily to the President, although the Senate must provide advice and consent for treaties with a two-thirds majority. Granting pardons is solely within the purview of the President, who has the authority to grant reprieves and pardons for federal offenses. The appointment of Supreme Court justices is also a presidential power, with the President nominating candidates and the Senate confirming them. Therefore, the ability to levy taxes is distinctly a power granted to Congress, establishing its role in the financial matters of the nation.
