Both A and C are potential answers, however A is the more appropriate answer. According to statement C, she could be commanding someone to do something, coming across as rude to the other. However, according to answer A, it would be saying Willa is being bossy by telling her what to do, which is more accurate. If the logic used to derive answer C was used on the other responses, it could be said that all were correct statements, but A is most definitely the most accurate answer out of all of them.
