AI Explanation

The correct answer is D) DSC is to be used for transmitting and receiving distress alerts to and from other ships or coast radio stations via radio. This is the primary purpose of DSC as it allows vessels in distress to quickly and automatically send a digital distress signal that includes the vessel's identity and location. This alerts other ships and rescue authorities, enabling a faster response to maritime emergencies. The other answer choices, while related features of DSC, are not its main intended purpose according to regulations governing maritime digital communications.
