Explanation Explanation for the correct answer: Option (b) is given as, vocal cords attach to the thyroid and arytenoid cartilages. Vocal cords are pairs of mucosal folds that extend from the pyramid-shaped arytenoid cartilages to the thyroid cartilages. An increase in the force of air that rushes across the vocal folds increases the vibrations of the folds, and then the sound intensity. Changes in the speed of air exhalation increases the tension of the vocal folds, hence increasing the pitch. Both these functions can be carried out because they are suspended between 2 sets of cartilages. Hence, option (b) is correct. Explanation for the incorrect answer: Option (a) is given as, vocal cords are same as the vestibular folds. Vestibular folds are false vocal cords that play no role in sound production except to enhance high-frequency sounds...
