DSC stands for Digital Selective Calling; which option correctly represents this acronym expansion?

Explanation:
Digital Selective Calling is a digital signaling method used in marine communications to place calls to a specific vessel or group using an MMSI. The expansion that matches the acronym DSC is Digital Selective Calling. The other phrases—Direct Satellite Channel, Data Synchronization Channel, and Digital Signal Code—do not correspond to the established maritime term, so they aren’t the correct expansion. DSC helps manage radio traffic by enabling targeted distress, urgency, and safety calls, and on VHF radios it’s commonly associated with channel 70 for initiating these digital calls.
