Which of the following video connectors can carry both audio and video?

DisplayPort is designed to carry both audio and video signals through a single cable, making it a versatile choice for modern displays and multimedia applications. This capability simplifies connections by reducing the number of cables needed to connect a device to a monitor or audio system. DisplayPort supports high-resolution video and high-fidelity audio and is frequently used in PCs and compatible monitors.

Other options, like VGA and DVI, primarily focus on video transmission. While DVI can carry audio when used in specific configurations (DVI-I), it is not as commonly utilized for this purpose in most setups. VGA, on the other hand, only transmits video and does not support audio in any form. IDE, being an older interface standard intended for connecting storage devices, is not relevant in the context of video and audio transmission. Therefore, DisplayPort stands out as the only option that effectively carries both audio and video signals.
