Which of the following connectors can be used to charge most modern mobile devices and may have the capacity to send data audio and video?

USB-C is the modern, reversible connector standard adopted by a vast majority of new mobile devices (including Android phones, tablets, and laptops). Its specification natively supports high-power charging via USB Power Delivery (USB-PD) and can transmit high-speed data, video (via DisplayPort Alternate Mode), and audio simultaneously over a single cable. This combination of features and widespread adoption makes it the correct answer.

A. The Lightning connector is proprietary to Apple devices and is not used by "most" modern mobile devices. It is also being phased out in favor of USB-C.

C. MicroUSB is an older standard that is largely replaced on modern devices. It lacks native support for video output and high-power delivery.

D. MiniUSB is an obsolete standard for mobile devices and has even more limited capabilities than MicroUSB.

Course materials often detail the evolution of USB, highlighting USB-C's multifunctional capabilities (power, data, video) as its key advantage over prior standards like Micro-USB.
