Final answer:
Beatrice demands that Benedick kill Count Claudio to prove his love for her in Shakespeare's 'Much Ado About Nothing'.
Step-by-step explanation:
In the play Much Ado About Nothing by William Shakespeare, Beatrice demands that Benedick prove his love for her by killing her cousin's accuser, Count Claudio.
This demand is spurred by Claudio's public humiliation of Hero, Beatrice's cousin, at their wedding, when he wrongly accuses her of being unfaithful.
Beatrice's demand represents her strong sense of family loyalty and the lengths to which she expects Benedick to go in order to demonstrate his love and commitment to her.
