D) Italian Sonnet
Hope this helps :)
If the options are metaphor, alliteration, allusion, and apostrophe, I believe the answer is metaphor, because the others don't fit.
Alliteration is the repetition of a consonant.
Allusion is reference to something or somebody outside of that literary work.
And apostrophe is the author speaking directly to somebody outside the poem, usually gods or a muse.
The correct answer for whoever may still need it is C. Her beauty and ease mark a darker reality.
