Which of the following is a barrier to effective communication?

• A. Communication Barriers
• B. Formal Communication
• C. Informal Communication
• D. Written Communication

Answer: (A)

Barriers to effective communication are anything that stops or distorts the message from being understood. Naming those obstacles directly as communication barriers makes this the best answer because it identifies the problem itself. These barriers can be physical noise, language differences, jargon, cultural misunderstandings, assumptions, or poor listening, all of which disrupt clarity and understanding.

Formal communication, informal communication, and written communication are all ways information is transmitted. They describe methods or channels, not obstacles. They can be effective or ineffective depending on the situation, but they are not, in themselves, barriers.
