(A) Exhalation (expiration) is the process by which air is expelled from the lungs.During exhalation:$(i)$ The diaphragm relaxes and moves upward to its dome-shaped position.$(ii)$ The external intercostal muscles relax,causing the ribs and sternum to move downward and inward,which reduces the volume of the thoracic cavity.$(iii)$ This increase in pressure inside the lungs relative to atmospheric pressure forces air out of the lungs.Looking at the provided figures,Figure $A$ shows the diaphragm moving upward and the ribs moving inward/downward,which correctly represents the process of exhalation.
