Solution

The correct option is C Twice
Let the audio signal frequency be $f$ and the bandwith of amplitude modulation be $B$
The bandwidth of Amplitude modulation is Twice the frequency of audio signal
Signal bandwidth $B = 2 \times$ Audio bandwidth.
$\Rightarrow B = 2 f$
Therefore option $C$ is correct
