The answer you are looking for would be option A. The local school board.
Explanation:
The sentence given to us is "Let's change up the pep rallies and give the band more time to play". This seems like a semi-formal command that you would not come from one classmate to another or from a fellow cheerleader to another one as the language does not seem to match a student's. However, the language of the sentence is not formal enough to imagine a teacher or parent using it in a PTO meeting. Additionally, the context where this sentence should be used would match a local school board better. Therefore, the local school board is the correct answer.
