Which of the following cables can carry a video signal?

USB-C can carry a video signal because the USB-C connector supports Alternate Modes, most commonly DisplayPort Alt Mode, which allows the cable and port to transmit video (and often audio) to an external display. Many modern laptops, tablets, and phones use USB-C to output video to monitors, TVs, and docks. In addition, some USB-C ports support Thunderbolt (depending on the device), which can also carry display signals along with data and power. This makes USB-C a versatile “single-cable” solution for charging, data transfer, and external display connectivity—an important concept in CompTIA A+ Core 1 when identifying connector capabilities and choosing the correct cable type.

The other options are not the best answer for standard video output in typical PC support scenarios. USB-A is a common data connector but does not natively carry a direct video signal like HDMI or DisplayPort (it would require an adapter that converts USB data to video). MicroUSB and MiniUSB were mainly designed for data and charging on older devices; while certain proprietary/legacy implementations existed, they are not the primary, modern, or expected video-carrying cable type in A+ objectives. Therefore, USB-C is the correct choice.
