What is the effect of the poetic structure used in each stanza of "The Raven"?


The absence of rhyme at the end of the first and third lines creates a disorganized tone.

The ending rhyme scheme in the last three lines gives the poem a monotonous tone.

The use of an internal rhyme scheme creates an inviting and almost playful tone.

An ending rhyme scheme that repeats in the refrain gives the poem a relentless tone.
