B Correct answer
Explanation

Digital phones convert voice signals into binary code (1s and 0s) using compression algorithms like vocoders. This digital compression allows multiple calls to be transmitted simultaneously on the same frequency through techniques like TDMA or CDMA, unlike analog phones that require dedicated frequencies.
