Solution
The correct option is C C and D are correct; while A and B are wrong.
The larynx is the voice box, which is the enlarged part of trachea."Adam's apple" is the protruding cartilage of the voice box of male humans.The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally. There are taste buds on the epiglottis.
Pleura is one of the two membranes around the lungs. These two membranes are called as the visceral and parietal pleurae. The visceral pleura envelops the lung, and the parietal pleura lines the inner chest wall. There is normally a small quantity (about 3 to 4 teaspoons) of fluid that is spread thinly between the visceral and parietal pleurae. The pleural fluid acts as a lubricant between the two membranes.
So, the correct answer is option C.
