Which interface does HDMI represent?

The correct choice is High-Definition Multimedia Interface. HDMI refers to a standard for transmitting high-definition video and audio from a source (like a Blu-ray player or gaming console) to a display (like a TV or projector) via a single cable. This interface supports various resolutions and audio formats, making it a universal connection for modern media consumption.

The term "multimedia" is specifically relevant because HDMI is designed to carry both audio and video signals simultaneously, which is integral to the multimedia experience. Other incorrect options misrepresent the terminology or fail to include "multimedia," which is a key aspect of what HDMI encapsulates.
