What type of connection does a USB-C port support?

A USB-C port is designed to be a versatile and universal connection standard that supports multiple functionalities, making option C the correct choice. One of the most significant features of USB-C is its ability to handle video and audio transmission along with data transfer and power delivery. This capability is made possible through the USB Power Delivery (USB PD) protocol, which allows for higher power levels for charging devices, as well as the ability to transmit high-definition video and audio signals.

For example, USB-C can be used to connect devices such as monitors, which require video signals, to laptops or smartphones, while also supporting audio output simultaneously. This makes USB-C an ideal choice for modern devices that aim to simplify connections by combining several functionalities into a single port. It streamlines the experience for users by reducing the number of different cables and connectors required for various functions.

In contrast, the other options specify only a single function—data transfer, audio only, or power only—neglecting the full range of capabilities that a USB-C connection provides. This multifunctionality is a key aspect that differentiates USB-C from previous USB standards, where one port typically could not support multiple data types concurrently.
