Final answer:
Congress has the power to declare war, as stated in the U.S. Constitution. This power, along with others such as making laws and regulating commerce, is part of the enumerated powers of Congress. The power to veto laws is held by the President, not Congress.
Step-by-step explanation:
The question seeks to identify which option best shows the type of power possessed by Congress. The correct answer is that Congress has the power to declare war, which is an enumerated power in the U.S. Constitution. Other key powers of Congress include the ability to make laws, levy taxes, regulate commerce, and ratify treaties—though the latter is specifically a power of the Senate, the upper chamber of Congress.
Regarding the options provided:
- Option a, the power to veto laws, is actually a power held by the President.
- Option b, the power to declare war, is indeed a power of Congress.
- Option c, the appointment of ambassadors, is a duty of the President, with the Senate having the power to approve or reject such appointments.
- Option d, the power to enact constitutional amendments, is a collective power that requires action by both Congress and the states, with Congress proposing amendments and the states ratifying them.
Therefore, the power to declare war best demonstrates a power possessed by Congress.
