Solution

The correct option is C
Vestibular fold of the larynx

The vestibular folds are located above both sides of the glottis. They vibrate to an extent during phonation, speech and especially during vibrato singing. Although they do play a role in resonance, these false folds, unlike the true vocal folds, are not actually responsible for sound production. The false vocal folds also work with the epiglottis to create a seal, so that nothing goes down the trachea (windpipe) during swallowing.
