Answer: Option A

Explanation: The label A represents the nasal passage which is the passage from where the air enters the body.

This passage contains mucus membrane that helps to moisten the incoming air from the outer environment for the process of inspiration.

The moistening of the incoming air is necessary for the removal of the dirt and harmful substances that should not enter the lungs. The main function is to filter the air and then allow it to move further.
