An IT specialist compares Bluetooth and NFC technologies for mobile device connectivity. Which of the following statements accurately describes a key difference between the two?
A.
NFC is faster than Bluetooth when transferring large files between devices.
B.
NFC consumes more power than Bluetooth, making it less suitable for devices in which battery conservation is crucial.
C.
NFC requires pairing with the receiving host, whereas Bluetooth just needs the available connection.
D.
NFC works best within a few centimeters, but Bluetooth can connect devices that are up to 32ft (10m) apart.
NFC (Near-Field Communication)operates atvery short ranges — usually less than 4cm, and is ideal for quick, secure transactions like contactless payments.Bluetoothsupportslonger ranges (up to 10 meters or 32 feet)and is suited for ongoing connections like wireless headsets or file transfers.
Option A:Bluetooth is faster for large file transfers.
Option B:NFC usesless power, not more.
Option C:NFC doesnotrequire pairing — Bluetooth does.
