Which of the following best describes "non-verbal" communication?

The best description of "non-verbal" communication is indeed communication through gestures and body movements. Non-verbal communication encompasses a wide range of expressive behaviors that convey messages without the use of spoken or written words. This includes facial expressions, posture, eye contact, gestures, and even the physical distance maintained between individuals during interactions.

By using body language and other non-verbal cues, individuals can express emotions, attitudes, and reactions that may not be fully conveyed through verbal communication alone. For instance, a smile can indicate friendliness, while crossed arms might suggest defensiveness or discomfort. Understanding non-verbal communication is crucial in many fields, including law enforcement, where interpreting these cues can significantly impact interactions and outcomes.

The other choices provided do not accurately define non-verbal communication. Spoken words pertain to verbal communication, while written text is clearly a form of written communication. Lastly, communication that does not involve any human interaction does not fit the definition since non-verbal communication inherently requires a sender and a receiver to interpret the cues being presented.
