Final answer:

The paranasal sinuses are located within the sphenoid, frontal, and maxillary bones, making option D the correct answer.

Step-by-step explanation:

The bones that contain paranasal sinuses are the sphenoid bone, frontal bone, and maxilla. Paranasal sinuses are air-filled spaces found within these skull bones. The frontal sinus is the most anterior and is located in the frontal bone above the eyebrows. The maxillary sinuses are the largest, found in the right and left maxillary bones below the orbits. Lastly, the most posterior is the sphenoid sinus, which is located in the body of the sphenoid bone, beneath the sella turcica.
