An audio signal consists of two distinct sound: one a human speech signal in the frequency band of \( 200 \mathrm{~Hz} \) to 2700 \( \mathrm{Hz} \), while the other is a high frequency music signal in the frequency band of \( 10200 \mathrm{~Hz} \) to \( 15200 \mathrm{~Hz} \). The ratio of the AM signal bandwidth required to send both the signals together to the AM signal bandwidth required to send just the human speech is
(a) 2
(b) 5
(c) 6
