All of the following are characteristics of organic organizations except:

A) broadly defined job responsibilities
B) decentralized and shared decision making
C) heavy reliance on formal rules and regulations
D) authority structure with fewer levels in the hierarchy

Organic organizations are known for having a more flexible and adaptable structure, with broadly defined job responsibilities, decentralized decision making, and a flatter authority structure with fewer levels in the hierarchy. They rely less on formal rules and regulations and more on informal communication and relationships. Therefore, C, heavy reliance on formal rules and regulations, is not a characteristic of organic organizations.
