Final answer:
The most appropriate action for the teacher to take is using nonverbal cues to indicate that the behavior is unacceptable. Hence, option (D) is correct.
Step-by-step explanation:
The most appropriate action for the teacher to take in this situation is D. Using nonverbal cues to indicate to the student that the behavior is unacceptable. Instead of reprimanding the student verbally in front of the class (option A), which may embarrass the student and negatively impact their self-esteem, using nonverbal cues such as a stern look or gesture can effectively communicate to the student that their behavior is not acceptable.
Moving the student to a different seat (option B) or sending the student out into the hallway (option C) may not directly address the issue of distraction and could potentially disrupt the lesson further.
