Communication happens in two broad forms: the words themselves and everything that accompanies them without words. Verbal communication is the actual language we use, including spoken words and written text. Nonverbal communication covers signals that convey meaning without words—body language, facial expressions, gestures, eye contact, tone of voice, pace, and volume. Together these two cover how messages are created and understood. This pairing is the best answer because it accounts for both the linguistic content and the nonverbal cues that shape interpretation. Other choices mix categories that aren’t as comprehensive: focusing only on words ignores the powerful nonverbal cues; naming a channel instead of a kind of signal misses the distinction between content and delivery; and listing a single nonverbal cue with a vocal cue doesn’t describe the full range of nonverbal signals.
