(d) Pleura and ___________.

Answer 1

The correct answer is Pleura and lung covering.​

Pleura is a double membrane layer and space between the membranes (called the pleural cavity) is filled with a thin, lubricating liquid (called pleural fluid).​

The fluid allows the layers to glide over each other as the lungs inflate and deflate during respiration and it protects the lungs from friction.
