Correct answer & explanation
✓
USB-A: Used for connecting peripherals like keyboards and mice
USB-A connects peripherals like keyboards and mice; HDMI transmits video and audio. Common confusions: USB-C is often mistaken for USB-A, and DisplayPort for USB-C.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
USB-A: Used for connecting peripherals like keyboards and mice
Why this is correct
USB-A is the standard rectangular host connector found on PCs, hubs, and legacy devices; it provides a simple, non-reversible data and power link that is ideal for low-speed peripherals such as keyboards and mice. This connector has been the de facto PC peripheral port for decades, and its ubiquity makes it the typical match for HID devices. The statement is correct because it accurately identifies the primary, everyday function of USB-A.
- ✓
HDMI: Used for transmitting video and audio signals
Why this is correct
HDMI (High-Definition Multimedia Interface) is a digital interface specifically engineered to carry uncompressed video and multichannel audio over a single cable, using TMDS (or the newer FRL) signaling with integrated HDCP copy protection. It is the standard connection for monitors, TVs, projectors, and set-top boxes, where the primary need is high-bandwidth A/V transmission. Thus, the statement correctly pairs HDMI with video and audio signals.
- ✗
USB-C: Used for connecting peripherals like keyboards and mice
Why it's wrong here
Although USB-C can technically connect a keyboard or mouse, the statement is misleading because USB-C is a reversible, multi-protocol connector designed for far more than simple peripheral attachment—it supports USB 3.2/4 data rates, Power Delivery up to 240W, and alternate modes like DisplayPort and Thunderbolt. In a typical matching context, keyboards and mice are associated with the legacy USB-A connector, not the newer universal USB-C. The error is over-assigning a generic peripheral function to a connector whose distinctive features are speed, power, and versatility.
- ✗
DisplayPort: Used for high-speed data and power delivery
Why it's wrong here
DisplayPort is a display interface, not a general-purpose data and power bus; its primary purpose is transmitting video and audio to monitors, with features like multi-stream transport and adaptive sync. It lacks the native protocol for arbitrary data transfers or power delivery that USB-C provides through USB PD and alternate modes. The statement is incorrect because it swaps the roles—DisplayPort is for A/V, while 'high-speed data and power delivery' is a signature capability of USB-C.
- ✗
USB-A: Used for transmitting video and audio
Why it's wrong here
USB-A is a general-purpose peripheral bus connector and is not natively designed to transmit high-definition video and audio; it does not have dedicated TMDS lanes, and its bandwidth is far lower than HDMI or DisplayPort. While USB can carry audio via the USB Audio Class and limited video through DisplayLink adapters, that is a secondary, compressed solution, not the typical use. Thus, the pairing is wrong because video and audio transmission are the domain of HDMI or DisplayPort, not the classic USB-A port.
