How is the ensign lowered in the evening?

The correct choice is that the ensign is lowered ceremoniously. This practice is rooted in naval tradition and honors the flag as a symbol of the nation and the service members who stand for it. Lowering the ensign ceremoniously involves specific procedures, often accompanied by salutes and rituals, to show respect for the flag and what it represents. This approach emphasizes the importance of the ensign and conveys the values of dignity and honor associated with military customs.

The other approaches, although they may have their own contexts or situations where they could apply, do not align with the traditional military protocol associated with the lowering of the ensign, which prioritizes ceremony and respect.
