Answer:
The option which is most closely a theme of the passage is:
D. A name in itself lacks physical reality because it can be easily changed.
Step-by-step explanation:
As we know, Juliet and Romeo fall in love, but their relationship is forbidden due to the enmity between their families. The fact that she is a Capulet and he is a Montague seems to be insurmountable. But that is precisely what Juliet is questioning in this monologue. She is not her name. Romeo is not his. They are real people with real feelings, so there should be no need for a name to hinder them, prevent them from being with each other. If Romeo were to change his name, he would still be who he is. Again, his name does not define him.
