CIt refers to a wireless Personal Area Network (PAN) technology that transmits signal over short distances among cell phones, computers and other devices ✓ Correct

DIt provides communication for devices owned by a single user that work over a short distance

Correct answer: (C) It refers to a wireless Personal Area Network (PAN) technology that transmits signal over short distances among cell phones, computers and other devices

Explanation

Bluetooth is a wireless Personal Area Network technology that transmits signals over short distances among phones, computers and other nearby devices.

It uses short-range radio waves to connect devices without any cables.

The description of technology travelling with the user by downloading content onto a mobile device refers to mobile computing, not Bluetooth.

Any operation done without a hard-wired connection describes wireless communication in general, which is broader than Bluetooth.

Communication merely for one user's devices over a short distance is too vague, missing the wireless PAN definition.

Bluetooth typically works within about ten metres and is widely used for headphones and file transfer.
