A digital interface used for transmitting high-definition video and audio.

• A. DisplayPort
• B. USB-C
• C. VGA
• D. HDMI

Answer: (D)

This question tests recognizing a digital interface that carries both high‑definition video and audio on a single cable. HDMI is designed exactly for that purpose: it transmits video and audio in a single digital signal between consumer electronics like Blu-ray players, game consoles, TVs, and sound systems. It supports a range of high-definition resolutions and multi‑channel audio formats, and it’s widely adopted because it’s simple to connect—one cable handles both video and audio. DisplayPort can also carry video and audio and is common on many PCs, but HDMI dominates the home theater and consumer electronics space. VGA is an older analog standard and cannot carry digital audio. USB‑C is a versatile connector that can carry video and audio via alternate modes, but it isn’t defined primarily as the standard interface for HD video and audio in the way HDMI is.
