When you assess non-verbal communication, you observe a person's posture, body movement, facial expressions, eye contact, and

• A. Voice
• B. Smell
• C. Tone
• D. Gesture

Answer: (B)

Non-verbal communication uses what you can observe with the body to convey meaning: posture, movement, facial expressions, and eye contact are all visual cues that reveal how someone feels or what they intend. The missing piece here is gestures—hands, arms, or other body movements that accompany or reinforce what is being communicated. Gestures can emphasize a point, indicate agreement, or direct attention, shaping the overall message without words. Voice and tone are related to how something is spoken and are auditory cues, not visible ones, and smell isn’t a meaningful indicator of intention in this context. So gestures best complete the non-verbal cues described.
