Which J-series message is for an emergency point?

Explanation:
In Link 16, J-series messages carry point data, and one subtype is specifically used for emergencies. The emergency-point message is designed to broadcast a location that must be acted on immediately, with the coordinates flagged for high priority so other units adjust their plans or routes without delay. This subtype conveys the urgent location and its status, ensuring rapid coordination across the network. Other J3 messages handle routine point data—creating, updating, or removing standard points—without the emergency designation. So the emergency point is transmitted using the emergency-point subtype, which is why this option is the correct one.
