1) The portion of pharynx that communicate with the internal nares and Eustachian tubes is calle Nasopharynx.
- The eustachian tube is auditory tube that links nasopharynx to middle ear. It clears the mucus of middle ear into nasopharynx. Hence, option C.
2) Nasopharynx is situated above the soft palate and hence it only receives air, it does helps the inner ear to equilize the air.

3) Larynx is the cavity present in respiratory system, just after the laryngopharynx, and do coonect the pharynx to trechea.
Larynx is known as the voice box, and thus it is the primary site of voice production.
Larynx only recieves air as it is present below the epiglottis, that prevent the entry of food.
Larynx is present anterior to esophagus.
Hence option E) All are correct
4) The epiglottic is a single flap like laryngeal cartilage that helps to prevent the food and liquid to enter in larynx. Hence option A)
