C Correct answer
Explanation

The read-range of an RFID system depends on transmitted power, antenna size (tag and reader), and environmental factors like RF noise. Tag memory is purely a storage capacity feature - it doesn't affect how far the tag can be read from. The other factors directly influence signal strength and detection range.
