The question asks which statement is false of an online meeting, so the three true descriptions have to be separated from the one that misdescribes the medium.

"It does not incorporate non-verbal clues" is the incorrect statement. A video-enabled online meeting carries a substantial part of the non-verbal channel: facial expression, gaze, head nods, hand gestures, tone of voice, pauses and rate of speech all come through. What is reduced is a subset of those cues — full body posture, precise eye contact, interpersonal distance and shared physical space — so the correct description is that non-verbal cues are diminished, not that they are absent.

"It does not recognize space barriers" is true and is the defining advantage of the medium. Participants in different cities or countries join the same meeting, so geographical distance stops being a constraint.

"It can become multi-media communication" is true, since an online meeting combines audio, video, screen sharing, slides, documents and text chat within a single session.

"It can incorporate various means of interactivity" is also true — chat, polls, raised hands, reactions, breakout rooms and shared whiteboards all allow participants to respond.

Hence the incorrect statement is that an online meeting does not incorporate non-verbal clues.
