Answer 1

The correct option is A

Statement 1 is true and statement 2 is false

Pleura is the double layered protective membrane of the lungs. The pleural cavity, with its associated pleurae, aids the optimal functioning of the lungs during breathing. The pleural cavity also contains pleural fluid, which acts as a lubricant and allows the pleurae to slide effortlessly against each other during respiratory movements. There are no cartilaginous rings in the bronchioles.
