The correct answer to the question is option 'C', which refers to the wheel communication network. This type of network is also known as a centralized network, where all communication flows through a central person, usually a supervisor or a manager.

Explanation:

The wheel communication network is a type of communication network in which all subordinates under a supervisor communicate through the supervisor only. The supervisor acts as the central person in this network, as all communication flows through him/her. The following are the characteristics of the wheel communication network:

1. Centralized communication: In the wheel communication network, all communication flows through a central person or a hub. This person is usually a supervisor or a manager who is responsible for managing the communication flow among subordinates.

2. Limited communication: The wheel communication network limits the communication among subordinates, as all communication flows through the central person. This can lead to delays in communication and may affect the productivity and efficiency of the organization.

3. Hierarchical structure: The wheel communication network follows a hierarchical structure, where subordinates communicate with the central person, who then communicates with higher-level managers or executives. This structure ensures that the communication flow is controlled and directed towards achieving organizational goals.

4. Clear roles and responsibilities: The wheel communication network ensures that each employee has a clear role and responsibility, as all communication flows through the central person. This helps in avoiding confusion and misunderstandings among employees.

In conclusion, the wheel communication network is a centralized communication network in which all subordinates under a supervisor communicate through the supervisor only. This type of network is suitable for organizations with a clear hierarchical structure and where communication flow needs to be controlled and directed towards achieving organizational goals.

In wheel network, all subordinates under one superior communicate through him only as he acts as a hub of the wheel. the subordinates are not allowed to talk among themselves .
