Answer:
The correct answer is a) Nonverbal communications.
Step-by-step explanation:
Nonverbal communication is a communication process in which there is a sending and receiving of messages without words, that is, by means of signs, gestures and signs. It has no syntactic structure, so it is not possible to analyze sequences of hierarchical constituents. The messages can be communicated through kinesics (gestures, body language, posture, facial expression, eye contact, etc.) the language; the proxémica and the chronémica.
