Answer:
D. Chester wipes his tears on his shirt, dragging his backpack behind him.
Step-by-step explanation:
Option D is correct because it provides a subtle clue that Chester is feeling overwhelmed and stressed out.
Trying to wipe his tears away denotes he has been emotionally down and was actually reluctant and tired to carry his backpack. He had to drag it along.
When one is overwhelmed, the individual becomes defeated by emotions and it caused him to shed tears.
