<span>C. Give him a second chance and treat him more fairly</span>
Answer:
Well I know it will definitely make sense at least for someone that understands what you are writing about.
Explanation:
This might just be my own opinion but i think it really is true.
I think the bolded words would be "whom Mr. Stein chose". The clause whom Mr. Stein chose is an example of an adjective because the clause describes the word student. Student is the subject of the sentence and is a noun. An adjective describes a noun or another subject. an adverb describes a verb or another adverb.
