The United States Supreme Court is a federal court, meaning in part that it can hear cases prosecuted by the U.S. government. (The Court also decides civil cases.) The Court can also hear just about any kind of state-court case, as long as it involves federal law, including the Constitution. And any case can involve federal law. For example, a defendant’s challenge to the basis for a police search implicates the Fourth Amendment, and is therefore within the Supreme Court’s jurisdiction. (See Supreme Court: Presence is Required to Prevent Certain Home Searches.)
All of the powers listed here are powers of a national or federal government as they reflect the jurisdiction to declare war, collect taxes (though some provinces in Canada can collect some of the income taxes and also provincial sales tax as well), the power to issue money ie it is the federal govt that prints money and or makes it available for projects, though a provincial govt and probably state govt has control over some spending, and the power to raise an army is only federal and conducting diplomacy is also a federal function.
C would be the correct answer
