The correct answer is the pleural membrane.

The pleural membrane is a double-layered structure that surrounds the lungs and forms an airtight seal, preventing air from leaking out. It consists of the visceral pleura (which covers the lungs) and the parietal pleura (which lines the chest cavity). The space between them, known as the pleural cavity, contains pleural fluid, which reduces friction during breathing but does not directly make the lungs airtight.

So, while the pleural cavity is an important part of lung function, the pleural membrane is what ensures the lungs remain airtight.

The Correct Option Is A, Pleural Cavity.
While Plueral Membrane Is Fluid-filled, Plueral Cavity Is Air-tight.
