Answer:
B) As soon as we get to school tomorrow, Rita and I will read the list.
Step-by-step explanation:
This is the sentence that best concludes this passage. In this text, we learn that Rita and the speaker have done their best to be good at tryouts and that the list with the results will be posted tomorrow. It is likely that both characters are really looking forward to knowing whether they made it unto the team or not. Therefore, they will most likely look at the list tomorrow as soon as they get to school.
