The correct option is B Larynx
In humans, the larynx is called the voice box. The larynx (voice box) is located between the pharynx and the trachea. It has a framework of cartilage, that protrudes in the front of the neck and sometimes is referred to as Adam's apple. The larynx is considerably larger in the male than in the female; hence, Adam's apple is much more prominent in the male. At the upper end of the larynx are the vocal cords, which serve in the production of speech. They are set into vibration by the flow of air from the lungs.
