Answer:
B). The use of figurative language to describe a state of shock.
Step-by-step explanation:
As per the question, the use of rhetorical language in 'a slight breeze could have blown me over' most adequately substantiates the claim that the point of view adopted in the paragraph is of an individual who was extremely entertained by Mitch's outlook/costume. It displays the immediate reaction of surprise seeing Mitch dressed completely off theme costume. His twisted clothes have completely shocked the speaker and made him think if the message of dress-code being formal even reached him. Thus, option B is the correct answer.
