Solution
The correct option is C epiglottis The cartilaginous flap that prevents the entry of food into the glottis during swallowing is called epiglottis. It covers the entrance of the larynx so that food and fluids do not enter the windpipe and lungs.
The trachea is a part of the respiratory system. It is also called a windpipe. It connects the larynx with the bronchi of the lungs.
The hard palate consists of hard ridge-like structures called rugae. Rugae are supported by bones for holding the food that is under mastication.
The uvula is a hanging tear drop shaped structure that closes the nasopharynx during swallowing. It also releases thin saliva that is useful for the lubrication of the back of the mouth.
