Why each option
HDMI (High-Definition Multimedia Interface) is the only option listed that simultaneously carries both high-definition digital video and multi-channel digital audio over a single cable. DVI and S-Video carry video only and do not support audio.
HDMI was specifically designed to transport uncompressed high-definition video (up to 4K and beyond) and up to 8 channels of digital audio simultaneously through a single connector, using the TMDS signaling standard for both signal types. This makes it the standard interface for consumer electronics, monitors, and home theater equipment requiring combined AV transmission at high data rates.
DVI-D carries only digital video signals and has no provision for audio transmission in its specification.
S-Video is an analog video-only interface that separates luminance and chrominance signals but carries no audio whatsoever.
DVI-I carries integrated analog and digital video but, like all DVI variants, does not support audio transmission.
