B. PAN (Personal Area Network):

A PAN is a network established between devices in close proximity, such as between a smartphone and a Bluetooth headset.

Bluetooth technology is specifically designed for short-range communication, making it a type of PAN.

Incorrect Options:

A. MAN (Metropolitan Area Network): A MAN covers a city or metropolitan area and is not relevant to Bluetooth connections.

C. SAN (Storage Area Network): A SAN is used for large-scale data storage, unrelated to Bluetooth connections.

D. WAN (Wide Area Network): A WAN spans large geographical areas (e.g., the internet) and is not relevant to this scenario.

Key Takeaway: Bluetooth connections, such as those between a headset and a device, create a Personal Area Network (PAN).
