Answer:
Don Pedro plans to disguise himself as Claudio at the masquerade ball Option D: To help Claudio win over Hero
Step-by-step explanation:
There are series of instances of mistaken identity in 'William Shakespeare's' 'Much Ado About Nothing'.
As story unfolds, 'Don Pedro' decides to disguise himself as Claudio and speak to Hero about love and their marriage.
He pretends to be Claudio at the dance and confesses Claudio's love to Hero for him and ask him to woo her. He does so because he agrees to their match a lot.
Antonio's servant overheard this incident about Don Pedro disguising and informs Leonato of the same.
