B. She should submit her email to her superintendent so her request gets reviewed.
Kiara writes an email suggesting alterations to the academic calendar. The appropriate person needs to receive these changes and review them.
She might receive feedback to help her email get better if she sends it to her parents, friends, or classmates, but doing so won't actually change the academic calendar.
Kiara must send an email to her superintendent in order for her request to be considered. A superintendent is one of the highest-ranking officials in a school district with the authority to effect "real change." If Kiara's goal is to make a genuine change to the academic calendar, she should send an email to the superintendent for further review.
Therefore, our answer is B) She should submit her email to her superintendent so her request gets reviewed.
