Residual volume is the volume of air which remains in the lungs after the most forceful expiration. This residual air enables the lungs to continue exchange of gases even after maximum exhalation. Due to this, lungs do not collapse even after forceful expiration.

Explanation:
The alveoli are tiny air sacs in the lungs that are responsible for the exchange of oxygen and carbon dioxide during respiration. These air sacs are very delicate and can collapse easily when the lungs are emptied of air during expiration. However, the lungs do not collapse even after forceful expiration, because of the presence of residual volume.
Residual volume is the volume of air that remains in the lungs after a forced expiration. It is the air that cannot be expelled from the lungs even after maximum effort. The residual volume helps to keep the alveoli inflated and prevents them from collapsing.
The other options mentioned in the question are not relevant in this context. Inspiratory reserve volume is the amount of air that can be inhaled forcefully after a normal inhalation. Tidal volume is the amount of air that is inhaled or exhaled during normal breathing. Expiratory reserve volume is the amount of air that can be exhaled forcefully after a normal exhalation. None of these volumes have any role in preventing the collapse of the alveoli.
In conclusion, residual volume is the key factor that prevents the lungs from collapsing even after forceful expiration.
