What type of communication is primarily expressed through gestures, facial expressions, and body posture?

Nonverbal communication is the correct answer because it encompasses all forms of communication that do not involve spoken or written words. This includes gestures, facial expressions, and body posture, all of which convey messages, attitudes, and emotions without the use of language. Nonverbal cues can significantly enhance or alter the meaning of verbal messages, adding depth and context to interpersonal interactions.

In contrast, verbal communication relies on spoken language to convey messages and does not include the physical expressions or cues that characterize nonverbal communication. Written communication involves conveying messages through written words, which can lack the immediacy of gestures or expressions. Visual communication typically refers to the use of visual aids, such as images, charts, or infographics, to convey information and is not focused solely on the nonverbal expressive behaviors of individuals.
