Non verbal communication forms – UGC NET Question

Non verbal communication includes all human communication without words,such as facial expressions,gestures,posture and eye contact. These cues often convey emotions and attitudes more powerfully than verbal messages. The behaviours listed in the stem clearly fall under this category. Thus,the correct answer is non verbal communication.

Option A:
Written communication uses written symbols like letters or emails and does not directly involve facial expressions or posture. So it does not fit the description.

Option B:
Mass communication can be verbal or non verbal,but the term emphasises audience size and medium,not specifically body language.

Option C:
Formal communication refers to official status of messages,which might still rely on spoken or written words; the term does not single out the non verbal elements mentioned.

Option D:
Non verbal cues often support or contradict verbal messages,so teachers must be aware of their facial expressions and gestures,which is exactly what the stem highlights,making option D correct.
