In Acute Respiratory Distress Syndrome (ARDS),alveoli and Respiratory Bronchioles Fill

In acute respiratory distress syndrome (ARDS) ,alveoli and respiratory bronchioles fill with fluid as a result of which mechanism?

A) Compression on the pores of Kohn, thus preventing collateral ventilation
B) Increased capillary permeability, which causes alveoli and respiratory bronchioles to fill with fluid
C) Inactivation of surfactant and the impairment of type II alveolar cells
D) Increased capillary hydrostatic pressure that forces fluid into the alveoli and respiratory bronchioles
