Answer:
Emphasize the vast emptiness of the scene.
Step-by-step explanation:
P.B. Shelley' poem "Ozymandias" describes the ruined state of the great king Ozymandias. And despite the king's boastful nature of what he had done, the statue is all alone in the vast desert, with nothing else to show his 'great work' that he'd boasted about.
In the last two lines of the poem, alliteration occurs in "bound and bare" and also in "lone and level sand stretch". These words emphasize how empty the scene is, despite the boastful attitude of the ancient king. The alliteration words only show how lonely and sightless the scene of the statue really is.
Thus, the correct answer is the last/fifth option.
