What equipment is required for video chatting on a desktop?

The correct answer is related to the essential components needed for video chatting on a desktop. A webcam and speakers are crucial for facilitating the video and audio aspects of the communication. The webcam captures video of the user, allowing them to be seen during the chat, while the speakers produce audio from the other participants, enabling the user to hear the conversation clearly.

The other options do not directly address the requirements for video chatting. A microphone, while important for inputting a user's voice, is not mentioned in the correct choice but is typically integrated into the functionality provided by a webcam. Printers and scanners serve entirely different purposes related to document handling and are not relevant to video communication. Lastly, while a graphics card and mouse are important for computer functioning and interaction with the interface, they do not specifically support the video and audio components necessary for effective video chatting.
