Answer:
The correct answer is:
A. remain in the classroom, facing the children, and speak quietly with Mr. Caulfield
Explanation:
In my opinion, this is the most appropriate option since children should not be left alone in the classroom for their safety first. On the other hand, Students need to learn about respect for other people, in these cases it is important to previously advise that they should behave appropriately and remain silent as a sign of respect towards visitors in the classroom. In the answer option that proposes about going loudly to the teacher informing that she is interrupting the class, would be a way of underestimating the teacher's authority and would be a serious disrespect for her. And the last option would result in the same way that a group of students will be left unsupervised, so it is not an acceptable option either.
