C) First item is equal or nearly equal to the second item.
Alveolar Pressure
The pressure within the lung alveoli, which changes during different phases of breathing.
Inspiration
The process of drawing air into the lungs, an essential component of breathing and gas exchange in the respiratory system.
Expiration
The process of releasing air from the lungs through the respiratory system, also known as breathing out.

Final Answer :
B
Explanation :
During inspiration, the alveolar pressure must be less than atmospheric pressure to allow air to flow into the lungs, making it less than the alveolar pressure during expiration, where the pressure must be greater than atmospheric pressure to expel air.
