Which is an example of verbal communication?

Verbal communication involves the use of spoken or written words to convey messages, express thoughts, or interact with others. In this context, when an individual responds "Hello" to a greeting, they are using spoken language, which is the essence of verbal communication. This form of communication allows for direct interaction and can establish rapport, provide feedback, and foster relationship-building.

Other options illustrate forms of communication that do not involve spoken or written words. Shaking hands represents a nonverbal gesture often associated with greeting or acknowledgment, while moving away from a person or sitting quietly conveys nonverbal expressions such as disengagement or passive presence rather than articulating thoughts or ideas through speech.
