Powers specifically outlined in the constitution are known as a. enumerated powers b. implied powers c. reserved powers d. concurrent powers

These would be "enumerated powers." Implied powers derive from those that are enumerated, and have been understood through judicial review (one of the very first examples of implied powers). Reserved powers are those that are not inherent to the Federal government, but given to the states instead. Concurrent powers are those that are shared by both the Federal and State governments.
