Final answer:
Reserved Powers, which are not explicitly stated in the US Constitution, are the authority of states and the people, examples being the issuance of licenses and the regulation of intrastate commerce.
Step-by-step explanation:
The category of powers that is defined by being absent from the US Constitution is the Reserved Powers. This is option 4 in the question presented. Reserved powers, under the 10th Amendment, are those that are not specifically granted to the federal government by the Constitution, nor denied to the states. These powers are therefore 'reserved' to the states or the people. Examples of reserved powers include the power to issue licenses, and to regulate intrastate commerce.
