The correct answer is: C. Both A and B.
Channel capacity is the maximum amount of information that can be transmitted over a communication channel in a given amount of time. It is determined by the bandwidth of the channel and the signal-to-noise ratio.
Bandwidth is the range of frequencies that can be transmitted over a channel. The higher the bandwidth, the more information can be transmitted.
Signal-to-noise ratio is the ratio of the power of the signal to the power of the noise. The higher the signal-to-noise ratio, the clearer the signal and the more information can be transmitted.
If the bandwidth is too low, then not enough information can be transmitted. If the signal-to-noise ratio is too low, then the signal will be too noisy and not enough information can be transmitted.
Therefore, the channel capacity depends on both the bandwidth and the signal-to-noise ratio.
