Show answer and explanation

Answer: B. A stranger could try to send a virus or a mean file to your device.

Explanation: When Bluetooth is "Discoverable," your device is basically shouting, "I'm here! Talk to me!" to everyone nearby. This makes it easier for "Bluejacking" (sending unwanted messages) to happen.
