Bluetooth is a wireless communication technology that allows devices to connect and communicate with each other over short distances. It is commonly used for connecting devices such as smartphones, laptops, headphones, and speakers. Bluetooth supports both point-to-point and point-to-multipoint connections.

1. Point-to-Point Connections:
A point-to-point connection refers to a connection between two devices. In Bluetooth, this type of connection allows two devices to establish a direct link and communicate with each other. This is commonly seen when pairing a smartphone with a Bluetooth headset or connecting a laptop to a Bluetooth mouse. The devices create a secure connection and exchange data directly between them.

2. Point-to-Multipoint Connections:
A point-to-multipoint connection refers to a connection between one device and multiple devices. In Bluetooth, this type of connection allows one device to connect and communicate with multiple devices simultaneously. For example, a smartphone can be connected to multiple Bluetooth speakers or headphones, allowing the user to stream audio to multiple devices at the same time. Each connected device functions independently, receiving data from the source device.

3. Both (a) and (b):
Bluetooth supports both point-to-point and point-to-multipoint connections, which means it can be used for various applications. It provides the flexibility to connect devices in a variety of ways, depending on the specific requirements. This versatility makes Bluetooth a popular choice for wireless communication in various industries, including consumer electronics, healthcare, automotive, and more.

4. None of the mentioned:
This option is incorrect because Bluetooth does support both point-to-point and point-to-multipoint connections, as explained above. Bluetooth technology is designed to support various connection types and configurations to meet the needs of different applications and use cases.

In conclusion, Bluetooth technology supports both point-to-point and point-to-multipoint connections. It allows devices to establish direct connections with each other as well as connect to multiple devices simultaneously. This versatility makes Bluetooth a widely used wireless communication technology in many industries.
