The correct answer is D. DVI (Digital Visual Interface).
According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:
DVI is primarily a video-only interface that transmits digital or analog video signals from a source (like a computer) to a display.
Unlike HDMI or USB-C, DVI does not carry audio signals, making it strictly for video.
Why the other options are incorrect:
A. DisplayPort: Supports video and audio as well as other features such as daisy-chaining multiple monitors.
B. HDMI: Transmits both video and audio signals over a single cable.
C. USB-C: Can carry data, power, and video/audio signals depending on the device and protocol (e.g., DisplayPort Alt Mode).
