Why each option

Among the listed wireless communication technologies, Wi-Fi typically offers the longest effective range, often covering hundreds of feet in suitable environments.

ANFC

NFC (Near Field Communication) has a very short range, usually only a few centimeters.

BBluetooth

Bluetooth has a moderate range, typically up to 30 feet for most devices and up to 300 feet for high-power devices, which is still less than common Wi-Fi ranges.

CWiFiCorrect

Wi-Fi (IEEE 802.11) typically operates with a range of up to 150 feet (46 meters) indoors and significantly more outdoors, making it the longest-range option compared to NFC, Bluetooth, and Infrared.

DInfrared

Infrared (IR) communication requires line-of-sight and has a very limited range, usually a few meters.
