Datum is defined as which of the following?

Explanation:
Datum is a fixed reference point used to anchor measurements of position. In SAR and navigation, coordinates are reported relative to this stable origin so everyone uses the same baseline and interpretations remain consistent across teams and maps. It isn’t describing where someone is now, where they were last seen, or a predicted movement; those options describe dynamic positions or movement. By using a common datum, you ensure that locations line up correctly on different maps and reports, which is essential for coordinating searches and sharing information.
