What is an advantage of having a variety of receiver bandwidths from which to select?

1. AThe noise figure of the RF amplifier can be adjusted to match the modulation type, thus increasing receiver sensitivity
2. BReceiver power consumption can be reduced when wider bandwidth is not required
3. CReceive bandwidth can be set to match the modulation bandwidth, maximizing signal-to-noise ratio and minimizing interference
4. DMultiple frequencies can be received simultaneously if desired
