Explanation

RFID standard bands are Low Frequency at 125 kHz, High Frequency at 13.56 MHz and Ultra High Frequency around 800 to 900 MHz.

Low Frequency in Statement 1 is a defined RFID band used for short-range tags.

High Frequency in Statement 2 at 13.56 MHz is a widely used RFID band.

Ultra High Frequency in Statement 5 gives longer read range for RFID.

The Very Low Frequency of 25 kHz in Statement 3 is not a defined RFID band.

The Very High Frequency of 100 to 200 MHz in Statement 4 is likewise not an RFID band.
