Answer:
D) laughing after receiving a bad grade is the correct answer.
Step-by-step explanation:
Nonverbal communication refers to facial expressions, gestures, eye contact, tone of voice, body language, posture, and other forms that people use to communicate without using words.
Letter A is incorrect because by nodding when a question is asked would mean that the listener is paying attention.
Letter B would mean that the audience appreciated or liked the performance.
Letter C is also incorrect because by smiling, a welcome could be understood.
Finally, letter D is the correct answer because if a person laughed after receiving a bad grade, it might mean that the person is making fun of it or that the person did not understand.
