Explanation

Standard passive RFID tags have no onboard power source - they are powered entirely by the RF field emitted by the reader. This extremely limited power budget makes implementing cryptographic operations (such as encrypting data in transmission) technically very challenging. While active RFID tags have a battery and more capability, encrypting the RF transmission channel is still not a standard, widely-supported feature across typical RFID implementations and adds significant cost and complexity. Option B (environmental sensors) is readily available in active RFID tags. Option C (real-time tracking as assets move) is a standard RFID use case. Option D (unique identifiers) is one of the most fundamental features of every RFID tag - unique IDs are built into the standard.
