Answer: d. creates an administrative agency and gives the agency powers.
Explanation: Enabling Legislation is an act passed into law that allows the creation of an agency and defines the powers it has. For example, the National Institute of Health NIH is granted the right to fund research related to health. One of the criteria is that the research be peer-reviewed. This is enough to define the duties of the NIH, although it is not broad enough to determine the exact types of researches it can, for instance, not fund.
