Verified step by step guidance

Begin by identifying the location and function of the nasal complex within the skull. The nasal complex is a structure that includes the nasal cavity and the paranasal sinuses, which are air-filled spaces that help lighten the weight of the skull and contribute to voice resonance.

Understand the anatomy of the skull and the bones that contribute to the formation of the nasal complex. The lateral walls of the nasal complex are formed by several bones, including the inferior nasal conchae, which are small, scroll-like bones located on the lateral walls of the nasal cavity.

Review the specific roles of the bones listed in the problem. The occipital bone is located at the back of the skull and does not contribute to the nasal complex. The parietal bone forms the sides and roof of the cranium, also not contributing to the nasal complex. The frontal bone forms the forehead and part of the roof of the nasal cavity but not the lateral walls.

Focus on the inferior nasal conchae, which are part of the ethmoid bone and are crucial in forming the lateral walls of the nasal complex. These structures help increase the surface area within the nasal cavity, aiding in humidifying and warming the air we breathe.

Conclude by recognizing that the inferior nasal conchae are the correct answer as they specifically contribute to the formation of the lateral walls of the nasal complex, unlike the other bones listed.
