How does the imagery of the bell affect the mood of this stanza?

Down sank the bell with a gurgling sound;
The bubbles rose and burst around.
Quoth Sir Ralph, “The next who comes to the Rock
Won’t bless the Abbot of Aberbrothok.”

The bell sinks into the water with a gurgling sound, as if trying to sound one last warning; this creates an ominous mood.

The bell serves as a symbol of the destruction Sir Ralph will do to the town; it creates a mood of despair.

The bell endures, no matter what Sir Ralph tries to do; this creates a triumphant mood as good survives in spite of evil.

The bell rings loudly in celebration, creating a cheerful mood.
