Options:
A. a businessman wearing a suit to his corporate meeting.
B. applause during the end of a musical performance
C. cheering your favorite team during a big game
D. a public speaker delivering a congratulatory speech
The answer is option D "a public speaker delivering a congratulatory speech." Nonverbal communication are gestures, tons, body language, posture, etc... and option D the public speaker is giving a speech congratulating people which doesn't require nonverbal communication. It also isn't option A because a businessman wearing a suit to a meeting is body language letting his coworkers know he is serious and there to work. It isn't option C because posture, body language, and gestures will be used when your cheering for your favorite team during a game. It also isn't option C because gestures are being used to clap at the end of a musical performance.
Hope this helps.
