Answer: A - Nonverbal communication is very important for expressing ideas, as it can completely change the meaning of what the speaker is saying (for example, “Excuse me” accompanied by physical movement toward a person might mean something different from “Excuse me” accompanied by crossed arms and a frown). Nonverbal communication can also indicate when someone is lying about their feelings if facial expression or vocal tone contradict what the person said. However, it is not completely reliable, as people can fake tones and facial expressions and different people may argue about what a specific gesture (such as avoiding eye contact) might mean in a given situation.
