Which of the following statements about nonverbal messages is true?

A) They are not culture specific.
B) They cannot contradict verbal messages.

D) They convey more than verbal messages.

Nonverbal messages can convey a lot more than verbal messages as they involve body language, facial expressions, tone of voice, and other elements that can communicate emotions and attitudes. They are not always unconscious, as some nonverbal behaviors may be intentionally used to send a particular message. Nonverbal cues can also vary across cultures, making them culture-specific. Finally, nonverbal messages can contradict verbal messages, revealing underlying emotions or attitudes that are incongruent with the words being spoken.
