Answer:
The correct answer is A. Accumulation of air in the pleural space is known as pneumothorax.
Explanation:
The pneumothorax is the air inlet in the interpleural space: between the visceral and parietal pleura.
It causes a pulmonary collapse of greater or lesser magnitude, with its corresponding impact on the patient's respiratory and hemodynamic mechanics, where the origin may be external (perforation in the rib cage) or internal (perforation in a lung).
