Which feature best distinguishes video conferencing from an ordinary telephone conference call?

Video conferencing lets participants at different locations see and hear one another in real time over a network, whereas a telephone conference call carries only voice. Visual contact allows facial expressions, gestures and shared visuals, which makes the discussion closer to a face-to-face meeting.

  1. AParticipants at different locations can see each other in real time as well as hear each otherCorrect
  2. BOnly one participant is allowed to speak during the whole session
  3. CIt can be held only between two persons in the same building
  4. DIt does not need any network connection

Explanation

Video conferencing uses a network to transmit both audio and live video between participants at different places. A telephone conference carries voice alone. The other options are false: video conferences can have many participants, work across distant locations, and need a network.
