Solution

The correct option is C Assertion is correct but Reason is incorrect
During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle's Law.
So, the correct option is 'Assertion is correct but the reason is incorrect'.
