Which DSC frequency must cutters monitor?

Explanation:
DSC calls can come in on multiple bands, so cutters must listen on both the VHF distress channel and the MF DSC frequency. The VHF distress frequency is 156.525 MHz (Channel 70) for near‑shore DSC calls, while the MF DSC frequency is 2187.5 kHz for longer-range calls. Monitoring both ensures the vessel can receive distress, safety, and routine DSC messages from any station. The other options fail because they omit one of the needed bands or mix up the bands (2187.5 kHz is MF, not VHF).
