What does "tattoo" refer to in naval terminology?

In naval terminology, "tattoo" refers to the signal or the period that occurs five minutes before "taps," the evening bugle call signaling lights out. This period is typically used for last call, where sailors are given a brief opportunity to secure any remaining activities before settling in for the night. Understanding this term is essential as it highlights the structure of the daily schedule and the importance of discipline in naval life.

The other options, while they may pertain to military contexts, do not capture the specific definition associated with "tattoo" in the navy. A decorative insignia, a military parade, and a type of drill represent different aspects of naval culture and tradition but do not align with the established meaning of tattoo as a time signal.
