Consider the following passage from a critical analysis of a novel:
'The author’s use of colloquial diction imbues the narrative with authenticity, allowing readers to resonate deeply with the protagonist's struggles. However, this informal tone is juxtaposed with occasional florid descriptions that elevate moments of significance. Such a blend of dialects not only enhances character development but also reflects the complexity of lived experiences, challenging the notion of a singular narrative voice.'
Based on this passage, which option best identifies the effect of the diction in the author's writing?
