Answer:
The correct answer to the following question will be Option 3 (Professional bureaucracy).
Explanation:
- Professional bureaucracy is evidence that uncentralized organizations can be administrative. Their organizational function is reliable, culminating in "preconceived or repetitive actions, in essence, uniform."It's also very complicated, and so the operators who are doing it should be regulated.
 - Mintzberg's organizational framework categorization classifies the information-based organization where services and goods depend as a highly qualified bureaucracy on both the knowledge and expertise of experts.
 
The other alternatives are not related to the structure of the Mintzberg. So choice 3 is the correct answer.
