Mr. Gray is the  C. Protagonist in the story :)

"Sally was hardworking during the school year and happy-go-lucky in the summer."

Explanation:

This sentence is an example of direct characterization because it shows Sally's direct traits, such as hardworking. The opposite of this is "'Watch out, summer. Here I come!'", because we have to make an inference based on Sally's dialog. Hope this helps!
