Which of the following is a form of body language that is always present and often unconscious, providing a rich source of information?

Body language refers to non-verbal cues communicated through physical behaviors. The statement highlights that body language is "always present" and "unconscious," providing a "rich source of information." Let's evaluate the options: a) Facial impression (facial expressions) is a form of body language. While often unconscious and informative, specific facial impressions* can be fleeting or consciously controlled, and a neutral face might not convey a distinct "impression." b)* Tone of guest's voice is a paralinguistic cue, not body language. It relates to how words are spoken, not physical body movements. c) Posture is the way a person holds their body. It is always present (everyone has a posture, whether sitting, standing, or moving), is often unconscious, and provides a rich source of information* about a person's confidence, mood, or attitude. This aligns very well with the description. d)* Nervous moments describe a state or a period of time, not a specific form of body language itself. While nervousness can manifest through body language (like fidgeting or changes in posture), "nervous moments" is not the direct referent of body language. Considering the emphasis on being "always present" and "unconscious," posture is the most fitting answer as it is a continuous and often involuntary aspect of non-verbal communication. The correct option is c. The answer is: c. Posture 3 done, 2 left today. You're making progress.
