Why does beatrice say no to don Pedro?

Beatrice declines Don Pedro's advances primarily because she values her independence and is skeptical of romantic entanglements. She often uses wit and humor to challenge societal expectations about love and marriage, showcasing her strong character. Additionally, her previous experiences and interactions with Benedick, filled with banter and mutual respect, suggest that her heart lies elsewhere. Ultimately, Beatrice's rejection of Don Pedro reflects her desire for authenticity rather than a conventional relationship.
