Answer:
D) Decentralized
Step-by-step explanation:
Greenwave is not limiting the decision making authority to its top executive and in fact, is delegating responsibilities and decision making to its regional managers. This is a form of decentralized organization, where by definition =, decision making is not limited to the central level.
A bureaucratic organization on the other hand is highly formal and focuses intensely on the hierarchy. Top down management again is a centralized organization focusing on the ideals of the upper management. Free form is less centralized and focuses on team based decision making.
Hope that helps.
