Near-field communication (NFC) is a set of communication protocols for communication between devices over a short distance.

• A. Near-field communication (NFC)
• B. Bluetooth
• C. USB (A/B/C)
• D. Wireless

Answer: (A)

The statement is describing a technology that is designed for very short-distance, device-to-device communication using a defined set of protocols. This matches Near Field Communication, which is specifically built for close-range interaction and enables quick data exchange with minimal power, often at a few centimeters apart. Why this is the best match: NFC is defined as a short-range wireless technology that operates at close proximity, making it ideal for things like contactless payments or quick pairing. Bluetooth is also a wireless technology but works over much longer ranges and isn’t described as near-field. USB is a wired interface, so it’s not a wireless short-range protocol. The term “Wireless” is too broad and would not indicate the near-field, protocol-specific nature of NFC.
