B.

Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol.

The attack type being described here is Bluejacking, which is option B.

Bluejacking is a type of wireless attack where an attacker sends unsolicited messages or spam to Bluetooth-enabled devices within range. These messages can be in the form of text, images, or business cards, and they usually contain harmless content, such as greetings or advertising messages.

The purpose of Bluejacking is not to harm the device or steal information, but rather to annoy or harass the user. Bluejacking can be carried out using simple tools, such as a Bluetooth-enabled phone or laptop, and it doesn't require any special skills or technical knowledge.

To perform a Bluejacking attack, the attacker first identifies nearby Bluetooth-enabled devices using a scanning tool. Once a target device is identified, the attacker sends an unsolicited message to the device using the Bluetooth connection. The message usually appears as a notification or pop-up window on the target device's screen.

Bluejacking is a relatively harmless attack, but it can be a nuisance to the victim. To protect against Bluejacking, users should disable the Bluetooth function on their devices when not in use, or set their devices to "invisible" mode to prevent them from being discovered by other Bluetooth devices.
