The answer is "D.Some powers are expressly given to the federal government under the Constitution."

 DELEGATED powers are particularly allowed to the national government in Article I, Section 8 of the Constitution. This incorporates the ability to coin cash, to manage business, to proclaim war, to raise and keep up military, and to set up a Post Office.  

IMPLIED POWERS are not particularly expressed in the Constitution, but rather might be construed from the flexible (or "essential and appropriate") statement (Article I, Section 8).  

INHERENT POWERS are not particularly recorded in the Constitution, but rather they develop out of the specific presence of the national government.
