Explanation:

Nonverbal communication is the one that involves transferring the message through the signal and doesn’t involve speaking. It includes gestures, facial expressions, movements and postures, eye contact, etc. Therefore, it is often including the physical manner or relation to another person and the signal of the body. It should not rely on the oral and spoken language and its knowing, but on the indications and gestures that are familiar to a wide array of people.

Holding the finger over the mouth or nodding are the gestures understood as communication in many cultures. First is used to silence someone, while nodding usually means yes or allowance. This is why this option is correct.

All other options are not the gestures and often include verbal components. Even mouthing words to someone is based on the knowledge of the language – while the sound isn’t heard, it involves recognition of the words gestures by the mouth.
