Answer:
The correct answer is a delegation.
Step-by-step explanation:
The delegation is, in administrative law, the transfer by an entity or body superior to another of lower level of the exercise of a competition, with the delegate retaining ownership of it.
The delegation assumes, of course, that the delegating authority is empowered by law or regulation to carry out the delegation. The act of delegation, however, is verified by virtue of a specific administrative act. For this same reason, the delegation is essentially revocable by the delegating authority.
