The personification of the stars in the poem, where they are described as "twinkling lazily" and "yawning," helps to convey a sense of exhaustion and the prolonged nature of the night. This imagery emphasizes the speaker's struggle to find rest and suggests that even the stars, typically associated with beauty and wonder, are weary.
Therefore, the best answer would be:
D. It creates a feeling of being wide awake at night.
This option captures the essence of how the personification of the stars reflects the speaker's own sleeplessness and the length of the night.
