Answer:
Greater than the pressure in the atmosphere.
Explanation:
Air moves from the region of higher pressure to that of its lower pressure. To move the air out of the lungs during exhalation, the intrapulmonary pressure (pressure inside the lungs) is increased above the atmospheric pressure. This is achieved by relaxation of the diaphragm and the external intercostal muscles relax. The chest and lungs recoil and the alveolar pressure inside the lungs increases above atmospheric pressure. This pressure gradient allows the air to move outside the lungs during exhalation.
The answer is most likely C. Can be used and consumed without risk.
