What equipment is associated with the land or terrestrial systems?

Correct Answer: Option B — VHF-MF-HF

Terrestrial radio systems utilize ground-based infrastructure for communication. VHF, MF, and HF radio installations, equipped with Digital Selective Calling (DSC), form the backbone of terrestrial GMDSS. These systems allow for direct ship-to-shore and ship-to-ship alerting within the coverage range of coastal radio stations and regional networks.
