Who said, "O Romeo, Romeo, wherefore art thou Romeo?"

The quote "O Romeo, Romeo, wherefore art thou Romeo?" is spoken by Juliet in William Shakespeare's play "Romeo and Juliet." This line is from Act 2, Scene 2, often referred to as the balcony scene. Juliet is expressing her anguish over the fact that Romeo is a Montague, the family her own family, the Capulets, are feuding with. Her use of "wherefore" means "why," questioning why Romeo must be a Montague. The other options, Julius, Caesar, and Mary Arden (Shakespeare's mother), are incorrect; Juliet is the correct character who utters these famous words.
