The correct answer is C. LAN and PAN.
A sensor is a device that detects and responds to some type of input from the physical world. Sensors are used to measure a wide variety of physical quantities and convert them into electrical signals that can be read by other devices.
A LAN (local area network) is a computer network that interconnects computers within a limited geographical area such as a home, office, or small group of buildings. A PAN (personal area network) is a computer network that connects personal devices such as mobile phones, laptops, and personal digital assistants (PDAs).
Both LANs and PANs are used to connect sensors to other devices. LANs are typically used to connect sensors to computers, while PANs are typically used to connect sensors to mobile devices.
HAN (home area network) is a network that connects devices in a home, such as computers, printers, and televisions. HANs are typically used to share data and resources between devices.
However, HANs are not typically used to connect sensors. This is because HANs are typically designed for short-range communication, while sensors often need to communicate over long distances.
Therefore, the correct answer is C. LAN and PAN.
