Explanation

NFC (Near Field Communication) has a maximum effective range of approximately 10 centimeters (about 4 inches). This short range is by design for security and ease of use, requiring close physical proximity between devices. Options A (100 cm) and B (10 meters) describe ranges more typical of Bluetooth or RFID. The 10 cm limit ensures NFC communication is intentional and minimizes accidental interactions.
