Answer:
The excerpt from "Romeo and Juliet" that is an example of personification is:
C. Still-waking sleep, that is not what it is!
In this line, Shakespeare personifies sleep by describing it as "still-waking," suggesting that sleep is hesitant or reluctant, which is not its usual nature. Personification is the attribution of human qualities to non-human entities, and in this case, sleep is given the human quality of being indecisive or uncertain.
Hope this helps..
Have a nice day!!
