Question

lookouts use what type of bearing when making reports? true magnetic relative gyro

Explanation:

In maritime (and related lookout) operations, relative bearing is used for reports. Relative bearing is measured relative to the vessel's own heading (e.g., 0° is ahead, 90° is starboard beam, etc.), which is practical for lookouts to report targets' positions relative to their own ship. True bearing is relative to true north, magnetic to magnetic north, and gyro is related to gyrocompass (less practical for direct lookout reports compared to relative).

Answer:

C. Relative
