Answer: D. It creates humor and surprise that the once enemies fell in love and marry.
Step-by-step explanation:
The sequence of events described in the text, where Beatrice and Benedick initially despise each other and both express disdain for romantic love, but later fall in love and marry after being tricked by their friends, creates humor and surprise.
Option D, "It creates humor and surprise that the once enemies fell in love and marry," captures this effect well. The fact that the characters who once vehemently opposed each other's romantic notions end up falling in love is unexpected and humorous, adding a touch of irony and entertainment to the story. This turn of events surprises the audience and adds an element of comedic tension to the play.
