In the context of the 12 o'Clock report, what does "striking 8 bells" refer to?

"Striking 8 bells" refers to marking the change of watch, which is an important tradition in naval and maritime contexts. The expression originates from the bell system used to signal time on a ship. Bells are struck to indicate the passage of time, with a total of 8 bells signaling a full period of four hours, which corresponds to a shift or change of watch. This is significant because it helps ensure that personnel are aware of their duties and responsibilities at specific times, ensuring smooth transitions and continuous operational readiness.

The other options do not align with the established meaning of "striking 8 bells." For example, while training exercises and meal times are important scheduling elements on a ship, they do not specifically relate to the traditional bell system used to denote changes in watch duty. Similarly, reporting all personnel present is related to accountability but is not indicated by the bell system.
