Which is an example of nonverbal communication?

Using facial expressions and gestures to make a request exemplifies nonverbal communication because it relies solely on physical actions and visual cues rather than spoken or written words. Nonverbal communication includes a variety of methods such as body language, facial expressions, eye contact, and hand gestures, all of which can effectively convey messages without the use of verbal language.

In contrast, naming the days of the week involves verbal communication, specifically the use of spoken words. Singing out loud at mealtime also represents verbal expression through music rather than nonverbal cues. An individual's hearing loss is a condition that affects auditory communication but does not inherently constitute a form of communication. Therefore, the act of using facial expressions and gestures is a clear and effective example of nonverbal communication that can enhance interpersonal interactions and understanding.
