Which interface carries both video and audio for displays?

• A. DisplayPort
• B. VGA
• C. HDMI
• D. DVI

Answer: (C)

The main idea here is identifying which display interface can carry both video and audio on a single cable. HDMI is designed to transmit digital video along with audio in one stream, so you can connect a source device (like a computer, Blu-ray player, or game console) to a display and get both picture and sound without a separate audio cable. This makes HDMI the go-to choice for setups that require audio and video over one connection, especially with TVs and monitors. VGA carries only analog video, so it doesn’t handle audio. DVI is primarily video-only in most implementations. DisplayPort can carry audio as well, but HDMI remains the most common standard for combined video and audio in consumer displays, which is why it’s the best choice here.
