B Correct answer
Explanation

NFC operates at 13.56 MHz, which is an internationally standardized ISM band frequency. This frequency is shared with other proximity technologies like high-frequency RFID. Options A (125-134 KHz) represents low-frequency RFID, not NFC. Option C (400-900 MHz) is used for UHF RFID and other wireless technologies. 13.56 MHz is the globally harmonized frequency for NFC operations.
