Final Answer :
A
Explanation :
The pleural fluid between the parietal and visceral pleura acts as a lubricant, allowing the lungs to move smoothly against the thoracic wall during respiration. It also creates a surface tension that helps in keeping the lungs expanded against the thoracic wall, ensuring that they expand as the thorax expands.
