Which are considered physical forms of communication?

The correct answer identifies posture and facial expressions as physical forms of communication. This form of communication falls under non-verbal cues, which convey messages through body language, gestures, and facial movements. These physical expressions often accompany verbal communication, but they can also stand alone, delivering meaning without words. For example, a smile can express friendliness or approval, while crossed arms might indicate defensiveness or disagreement.

In contrast, other options such as words and phrases are verbal forms of communication, using language to convey messages. Written notes are also a verbal form, as they involve the use of written symbols to share information. Technical jargon refers to specialized language used by a specific group, which is again verbal rather than physical. Thus, it’s clear that the physicality of posture and facial expressions is what distinguishes the correct answer in this context.
