The correct answer is d) favor one state over another.

To arrive at this answer, you need to be familiar with the powers granted to Congress in the US Constitution. These powers are outlined in Article I, Section 8 of the Constitution, which enumerates the specific powers vested in Congress.

a) Regulate foreign and interstate trade: This power is granted to Congress under the Commerce Clause, allowing them to regulate commerce with foreign nations, among the states, and with Native American tribes. This power has been broadly interpreted by the courts to encompass various aspects of trade and economic activity.

b) Coin money: The Constitution explicitly grants Congress the power to coin money and regulate its value. This power is outlined in Article I, Section 8, Clause 5. However, note that Congress does not have the exclusive power to issue currency, as the Federal Reserve System plays a significant role in the modern monetary system.

c) Declare war: The power to declare war is vested in Congress as stated in Article I, Section 8, Clause 11. This means that only Congress can formally initiate a state of war, although the President, as commander-in-chief of the military, has the authority to engage in military action without a formal declaration of war.

d) Favor one state over another: The Constitution does not grant Congress the power to favor one state over another. The principle of equality among states is a fundamental tenet of the US Constitution, and any legislation deliberately and exclusively benefiting one state at the expense of others would likely be deemed unconstitutional.

So, in summary, the power that Congress does not have according to the US Constitution is d) favor one state over another.
