__ describes every type of human communication that is not verbal.a.vocalistsb.para languagec.hapticsd.All of the given options

To answer the question regarding the non-verbal types of human communication, we need to analyze the given options:

1. Vocalists: This term typically refers to individuals who sing or produce music using the voice. It does not capture the essence of non-verbal communication.

2. Para language: This term refers to the aspects of communication that accompany verbal language, such as tone of voice, pitch, and volume. It is more about vocal qualities than communication that is strictly non-verbal.

3. Haptics: This term pertains to communication through touch, which is indeed a form of non-verbal communication.

4. All of the given options: This choice suggests that all previous options are types of non-verbal communication.

Given this analysis, the most appropriate answer would be c. haptics, as it specifically identifies a category of non-verbal communication. However, if looking for a broader term that encompasses non-verbal communication in different forms, including gestures and facial expressions, none of the options perfectly fit.

Final Answer

• The correct answer is c. haptics.
