Answer:
C. The author uses first-person point of view to show that Jake wants to hide his emotions from Monique
Solution:
Reading the last sentence, we can see that Jake has "millions of butterflies swimming in his stomach", and from earlier text, we can also see that Monique is nervous as well. We know it is not D, because both Jake and Monique are very nervous, and the story is told from 1st person POV. So choice C is the best option.
EDIT: Spelling and grammar
