Correct Answer:
B. Informal communication
Communication within organizations occurs through various channels, broadly categorized as formal and informal. These channels serve different purposes in information dissemination.
The correct answer is B: Informal communication. The grapevine refers to the unofficial, spontaneous, and often word-of-mouth communication network that exists within an organization. It's characterized by its lack of formal structure and its rapid, though sometimes inaccurate, spread of information, rumors, and gossip among employees.
- A: Formal communication follows established organizational hierarchies and official channels, which is the opposite of the grapevine.
- C: Written communication is a format, but the grapevine is predominantly oral and unofficial, not primarily defined by being written.
- D: External communication involves transmitting information between the organization and outside entities (e.g., customers, media), whereas the grapevine operates internally among employees.
