Respuesta :

Dante is in Hell, a place of eternal suffering. Today, we joke about going to Hell, but Dante is creating an atmosphere of despair that is not a joking matter. The "everlasting air" is creating the sense that there is no escape from Hell. The word tremble is used as imagery to stimulate our sense of touch. 

The correct answer is C) unrest and discomfort.

The kind of mood that Dante's line "sighs that caused the everlasting air to tremble" set is of "unrest and discomfort."

We are referring to the passage of the famous novel "The Divine Comedy," written by Italian writer Dante Alighieri, from 1308 to 1320. The passage is from Inferno, Canto 4, LIne 26, Circle 1, that says; "Here, for as much as hearing could discover, there was no outcry louder than the sights that caused  the everlasting air to tremble."

The other options of the question were A) tranquility and peace. B) retribution and revenge. C) betrayal and punishment.
