The correct answer is : A cheerleading squad
Explanation: The term Pep Rally is widely used among Americans to name concentrations that take place before a basketball or soccer game in college or high school. In this concentration there are students, players, cheerleaders, bands, animators, meet to sing, shout, cheer and fill with optimism and energy for the game that will take place.
The answer you are looking for would be option A. The local school board.
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.
I think is letter C
Good luck hun!
