To conduct a basic video chat, which hardware setup is sufficient?

• A. Scanner
• B. Webcam and speakers so that he and his mother can both see and hear each other.
• C. Webcam, monitor, and keyboard for viewing and typing
• D. Projector and webcam for clear visuals and audio

Answer: (B)

For a basic video chat you need something to capture video and a way to handle audio. A webcam provides the video so the other person can see you, and speakers let you hear them. In most setups the computer’s built-in microphone (or the webcam’s mic) handles your side of the audio, so you can speak back. This minimal pairing covers both video and audio without extra gear. The other options don’t fit because they omit video, or audio input, or add unnecessary equipment like a scanner, keyboard/monitor combo, or a projector.
