Final Answer :
D
Explanation :
The septum is a structure in the nasal cavity, but it is not a paranasal sinus. The paranasal sinuses are air-filled spaces within the bones of the skull that communicate with the nasal cavity and serve various functions such as humidifying and filtering air, as well as reducing the weight of the skull. The maxillary sinus, frontal sinus, and ethmoidal sinus are all examples of paranasal sinuses.
