A Correct answer
Explanation

The vocal cords (also called vocal folds) are the primary vibrating structures that produce sound in humans. When air passes through the larynx, the vocal cords vibrate, creating sound waves. The pharynx and windpipe help transmit sound, while lungs provide air, but only the vocal cords actually vibrate to generate sound.
