Correct Answer: Option D — Course over ground and MMSI
Course over ground and the Maritime Mobile Service Identity (MMSI) number are dynamic and high-priority identification parameters respectively. MMSI is broadcast continuously, while COG updates dynamically within the mandatory 1 to 10 second interval for active collision avoidance tracking.
