The choice that identifies a wireless connection method supporting both data transmission and power supply is USB. This is particularly relevant in the context of technologies like Wireless USB, which allows for high-speed data transfer and the capability to deliver power to devices without requiring a physical connection.

USB technology has evolved to include the ability to transfer power along with data, which is essential for operating devices that may not have their own power sources, or to charge devices simultaneously as they are used for data transfer. This feature is especially prevalent in USB-C, which supports power delivery, allowing devices to be charged and transmit data over a single cable.

In contrast, HDMI primarily focuses on transmitting high-quality audio and video signals and does not support power delivery in the same way. LAN typically refers to local area networks and relies on wired connections that may provide power through Power over Ethernet (PoE) but are not wireless. Ethernet is also a wired technology designed specifically for data transmission, without features for powering connected devices.
