Which of the following is NOT a power granted to Congress?

The correct answer is the option that states Congress does not have the power to grant pardons. The authority to grant pardons is specifically assigned to the President of the United States under Article II, Section 2 of the Constitution. This power allows the President to forgive individuals for federal offenses, effectively removing the penalties associated with those offenses.

In contrast, Congress is vested with several specific powers, including the ability to levy taxes, regulate commerce, and declare war. These powers are critical for the functioning and authority of the legislative branch, enabling Congress to manage economic policy, oversee interstate and international commerce, and make decisions about military engagements. Understanding the distinct roles and powers assigned to different branches of government is foundational to grasping the structure of the U.S. political system.
