Which communication method allows meetings via telecommunications networks where participants can see and hear each other?

• A. Open channels of communication
• B. Restricted channels of communication
• C. Verbal communication
• D. Video-conferencing

Answer: (D)

Video-conferencing allows meetings over telecommunications networks where participants can see and hear each other. It brings together real-time audio and visual communication, typically via webcams and microphones, so colleagues in different locations can interact as if they were in the same room. This enables discussion, collaboration, and the reading of non-verbal cues—things that are hard to do with audio-only methods. The other options don’t fit as well: verbal communication refers to spoken words (often audio-only), while open or restricted channels describe access and transparency rather than the ability to conduct a live, face-to-face-like meeting remotely.
