The word communication refers to an exchange of information or meanings by using signs usually from one person to another. Because of this, communication does not only involve written symbols or sounds but non-verbal communication such as gestures, body position or touch that implies meaning and information exchange. Examples of touch in communication or haptic communication include any physical contact that means something or deliver a message or information such as hugs, kisses, shakes of hands, pinching, etc. Therefore, all putting an arm around a grieving friend's shoulders, shaking hands with a new acquaintance or giving a teammate a high five after a great play are examples of touch in communication and thus, the correct answer is "all of the above".
