Final answer:
The tone of the poem discussed is best described as reflective, characterized by the somber, desolate setting and repeated rhymes that express dejection and an introspective mood. Therefore, the tone can best be described as reflective (Option C).
Step-by-step explanation:
The tone of a poem can often be identified by analyzing the poet's choice of words, phrases, images, and the overall mood created by the poem. In the provided example, where Mariana is waiting in a 'lonely, crumbling grange,' the tone is conveyed through repeated rhymes such as 'dreary'/'aweary' and 'dead'/'said,' which suggest dejection and the boredom of endless waiting, as well as the desolate setting. This sets a somber and reflective mood rather than a fearful, inspirational, or longing one. The repeated dreary aspects of the description, such as 'black moss' and 'rusty nails,' support the reflective and almost meditative nature of the poem as Mariana contemplates her situation. Therefore, the tone can best be described as reflective (Option C).
