Congress declares war on a country and the president sends troops would be against the constitution
Congress declares war on a country, and the president sends troops. That won't be good. Everything has to abide by the Constitution. The President, Congress, Senate, etc. all have to agree to do so.
Option D, where California begins to coin and print currency for use within the state, is against the Constitution because only Congress has the authority to coin money. The other options are all constitutional actions. Therefore, the correct choice is D.
