"But, soft! what light through yonder window breaks? / It is the east, and Juliet is the sun." aSimile bPersonification cAllusion dMetaphor

The quote you provided is from William Shakespeare's play "Romeo and Juliet". In this quote, Romeo is comparing Juliet to the sun. This is a form of figurative language.

The options you provided are different types of figurative language:

a) Simile: A simile is a comparison using "like" or "as". b) Personification: Personification is giving human characteristics to non-human things. c) Allusion: An allusion is a reference to a well-known person, place, event, literary work, or work of art. d) Metaphor: A metaphor is a direct comparison between two unlike things.

In the quote, Romeo is not using "like" or "as" for the comparison, so it's not a simile. He's not giving human characteristics to a non-human thing, so it's not personification. He's not making a reference to a well-known person, place, event, literary work, or work of art, so it's not an allusion.

Therefore, the correct answer is d) Metaphor. Romeo is making a direct comparison between Juliet and the sun.
