An audio signal consists of two distinct sounds: one a human speech signal in the frequency band of \[200\text{ }Hz\] to \[2700\text{ }Hz,\] while the other is a high frequency music signal in the frequency band of \[10200\text{ }Hz\] to \[15200\text{ }Hz\]. 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. \[6\]
• D. \[3\]
