Verified step by step guidance

Step 1: Begin by understanding the anatomy of the nasal cavity. The nasal cavity is a hollow space within the nose that is divided into two compartments: right and left.

Step 2: Identify the structure responsible for dividing the nasal cavity. The nasal septum is a vertical partition made of bone and cartilage that separates the nasal cavity into right and left compartments.

Step 3: Review the other options provided in the question to ensure clarity: The ethmoid sinus is a group of air cells within the ethmoid bone, the hard palate forms the roof of the mouth, and the nasal conchae are curved bony structures that increase surface area within the nasal cavity but do not divide it.

Step 4: Confirm that the nasal septum is the correct answer based on its anatomical function of dividing the nasal cavity into two compartments.

Step 5: Reinforce the concept by visualizing or referring to an anatomical diagram of the nasal cavity to see the nasal septum's location and role in separating the compartments.
